Compare Roof Window Seal and Draught Repair Quotes in West Sussex
Cold air entering around a roof window can make a loft room uncomfortable and increase heat loss during winter. Our free matching service connects property owners throughout West Sussex with independent contractors who repair roof window seals and draughts.
Tell us where the draught is coming from, what type of roof window you have and where the property is located, and we will try to match the enquiry with up to four specialists. You can then compare the proposed repairs, replacement seals, prices and timescales before deciding whether to proceed.
Air movement around a roof window can come from the sash, frame, ventilation flap, internal lining or gaps in the surrounding insulation. The inspection should consider both the moving window components and the fixed connection between the window and roof.
What Roof Window Draught Problems Can Specialists Repair?
Local contractors throughout West Sussex carry out gasket replacement, sash adjustment, insulation and air-tightness repairs. A contractor should explain where the draught is entering and why the proposed work is appropriate.
Roof Window Rubber Seal Replacement
Repeated opening, sunlight and temperature changes can gradually reduce the flexibility of roof window seals. The specialist should also check that the window closes evenly and applies the correct pressure to the replacement seal.
Roof Window Sash Seal Repairs
A gap between the sash and frame can allow cold air, wind noise and moisture into the room. The repaired window should be tested in both the closed and ventilation positions.
Roof Window Frame Seal Repairs
The gap may have been poorly insulated or sealed during the original installation. The work should avoid blocking drainage or ventilation components built into the window.
Roof Window Ventilation Flap Seal Repairs
A small amount of controlled ventilation may be normal when the vent is open. Homeowners should distinguish between designed background ventilation and uncontrolled air leakage.
Roof Window Hinge Adjustment
One side of the window may press firmly against the seal while another side leaves a visible gap. The sash should be checked for smooth movement and even contact after adjustment.
Roof Window Lock and Catch Adjustment
Worn catches, misaligned locking points or a damaged handle can leave the window slightly open. The window should lock securely without requiring excessive force.
Visible Gaps Around Roof Windows
A gap may appear only at one corner or along an entire side of the roof window. The correct repair may involve mechanical adjustment, compatible seals or rebuilding the internal lining.
Cold Roof Window Frame Repairs
Timber trimmers, metal brackets and gaps in the lining can create local thermal bridges. Improving the internal lining design may also reduce cold spots around the top and bottom of the window.
Missing Roof Window Insulation
Some older or poorly fitted windows have gaps between the frame and surrounding roof timbers. The new material should be fitted without distorting the frame or obstructing drainage details.
Roof Window Air-Tightness Repairs
Unsealed joints around plasterboard, vapour-control layers and internal collars can create noticeable draughts. A complete air-tightness repair should be coordinated with insulation and ventilation requirements.
Roof Window Condensation Repairs
Warm, moisture-laden air can condense on cold glazing, frames and internal reveals. Homeowners may also need to improve extraction, background ventilation or heating within the room.
Mould Around Draughty Roof Windows
Black spotting around a roof window may point to high humidity, poor insulation or uncontrolled air leakage. Damaged plasterboard may need replacing after the area has dried.
Roof Window Rattle Repairs
Worn seals, loose hinges, damaged locks or external covers can create movement and noise. The repair should address the movement rather than simply packing the gap with unsuitable material.
Rain Noise Through Roof Windows
Loose glazing, poor sash contact and gaps around the internal lining may increase sound transmission. Changing only a rubber gasket will not alter the inherent sound performance of the glass.
Roof Window Dust and Insect Ingress
The problem may be especially noticeable during windy or dry weather. The source of the entry should be confirmed before components are sealed.
Roof Window Whistling Noise Repairs
The opening may be caused by a flattened gasket, poor locking pressure or a gap in the internal lining. The window should be tested after the repair where weather conditions permit.
Roof Window Seal Shrinkage
Shortened gaskets leave small openings that allow draughts and moisture around the sash. The correct profile and length are important for creating an even seal.
Painted-Over Roof Window Seals
A sash may stick to the frame where decorating products have covered the gasket. The window should be allowed to close and open freely after decoration.
Roof Window Seal Damage After Cleaning
Abrasive tools may tear the gasket or remove protective finishes from the frame. The surrounding flashing should also be checked if water has been driven beneath the roof covering.
Draughts from Roof Window Blinds and Linings
Poorly fitted plasterboard and loose decorative trims can expose cavities around the frame. Replacing the sash gasket alone will not solve an air path behind the fixed frame.
Roof Window Draughts After Replacement
Problems can arise from incorrect frame alignment, missing insulation, damaged seals or incomplete internal air-tightness work. Any workmanship or product warranty should be reviewed before another contractor alters the installation.
Roof Window Draughts After Hinge Replacement
A window that did not draught before a repair may need further alignment or adjustment. The completed window should open, close and seal consistently.
Electric Roof Window Seal Repairs
The fault can involve the actuator, controls, hinges, seals or frame alignment. Electrical work should be completed by an appropriately competent person.
Solar Roof Window Seal Repairs
Incomplete closing can leave the sash unable to compress the weather seals. Worn seals should only be replaced after the closing fault has been corrected.
How to Tell If a Roof Window Seal Has Failed
A failed gasket is not always obvious until the temperature drops or wind reaches a particular side of the property.
A homeowner may suspect worn roof window seals where there is:
- Cold air around the sash
- A clear gap around one edge of the window
- Noise that changes with wind direction
- The sash rattling in the frame
- Seals that have hardened or pulled away
- A handle that no longer pulls the sash closed evenly
- Condensation around the frame
- Noticeable heat loss from the loft room
- Debris passing through the ventilation flap
- Heating being needed more often
- Moisture passing through a gap in the sash seal
- Gaps between the plasterboard and window frame
Types of Roof Window Seal Repair
The correct component depends on where the draught or moisture is entering.
Roof window sealing components can include:
- The main sash weather seal
- Seals holding the glass within the sash
- Seals controlling airflow through the ventilation opening
- Corner joints and gasket connections
- Sealing components between the frame and room lining
- Preformed or site-installed insulation around the opening
- External frame seals
- Routes that carry moisture away from the frame
- Catches and locking bars that hold the sash shut
- Hinges and support mechanisms
Replacement Seals for Leading Roof Window Manufacturers
Specialists may repair both current and discontinued roof window products. An identification plate is usually located on the sash or behind the ventilation flap.
Draughty VELUX Window Repairs
The VELUX product plate normally displays the window type, size and production code. Common model references include GGL and GGU centre-pivot windows and GPL and GPU top-hung models.
A cold VELUX window may also have an open ventilation flap, poor sash alignment or gaps in the internal lining.
FAKRO Gasket and Seal Replacement
FAKRO supplies timber and PVC windows with several opening and operating systems. Other products may include FTT high-performance windows, FWR or FWL access windows and FSP smoke ventilation units.
Keylite Gasket Replacement
Keylite manufactures centre-pivot, top-hung, fire escape, electric and conservation-style roof windows. The complete identification reference should be used when checking replacement components.
Roto Roof Window Gasket Replacement
Roto roof windows are fitted in many UK and European properties. Customers may refer to R4 pivot, R7 high-axis or R8 top-hung pivot models.
Dakea Gasket and Draught Repairs
Dakea produces pitched roof windows in centre-pivot, conservation and powered designs. Older ranges may have different component availability from current products.
RoofLITE Gasket Replacement
RoofLITE and RoofLITE+ windows are fitted in many domestic loft rooms and extensions. Compatible components may be available for some older units.
Discontinued Roof Window Seal Replacement
Some properties contain discontinued or unbranded roof windows with limited product information. Generic draught repairs may be possible, but unsuitable seals should not be forced into the frame.
Finding the Source of Air Leaks Around Roof Windows
The location where cold air is felt does not always identify the original gap.
Roof window draught diagnosis can involve:
- Check whether the air movement depends on wind direction
- Identify the roof window make and model
- Look for flattened, cracked or missing sections
- Look for gaps between the glazing and sash
- Check the ventilation flap
- Check whether the catches engage correctly
- Assess whether the sash sits squarely in the frame
- Look for visible daylight
- Look behind removable covers where appropriate
- Look for cold bridges around the roof opening
- Inspect air-tightness and vapour-control connections
- Assess whether moisture is linked to cold surfaces
- Confirm that the sash reaches its fully closed position
- Use smoke pencils or other non-destructive testing where appropriate
What Is Included in Roof Window Seal Repair?
The contractor should provide a clear description of the proposed repair after inspecting the window.
Roof window seal and draught repairs may include:
- Check the model, size and production code
- Carefully release the existing seal from its channel
- Clean the gasket channels
- Install a suitable replacement gasket
- Repair damaged vent-bar components
- Adjust hinges and sash alignment
- Restore closing pressure against the seals
- Ensure that a powered window reaches its closed position
- Remove internal trims where necessary
- Fill cold gaps in the roof opening
- Reduce uncontrolled air movement into the roof
- Refit or rebuild internal linings
- Check that the window opens, closes and locks correctly
- Leave the work area clear
Roof Window Gasket Repair or Replacement
A gasket that has simply moved out of its channel may not always need replacement. A complete compatible replacement generally provides a more reliable result where the original seal has deteriorated.
Seal replacement may be appropriate where:
- The gasket breaks when flexed
- There is little rebound in the rubber
- Sections are torn or missing
- The ends no longer meet
- Earlier decoration has bonded the gasket to the frame
- An incorrect seal was previously fitted
What Affects Roof Window Seal Repair Prices?
The total cost depends on the window, component availability, access and condition of the installation. A straightforward gasket replacement normally costs less than hinge, lock or internal lining work.
A roof window seal specialist will normally consider:
- Whether the window is current, discontinued or unbranded
- The number of seals requiring replacement
- Lead times for suitable gaskets
- The number of contributing faults
- The condition of hinges and locks
- Whether a powered closing fault must be diagnosed
- Whether external access is also required
- Internal lining removal
- Whether cold gaps need filling
- Repairs to hidden membrane connections
- Condensation or mould damage
- Whether several windows can be serviced together
- Clearance of components and packaging
Comparing detailed quotations is the most reliable way to establish a fair price for the work. Our free matching service makes it easier to compare roof window draught repair prices across West Sussex.
When Does a Draughty Roof Window Need Replacing?
Many draughty roof windows can be repaired without replacing the complete unit. An older roof window with poor glazing and repeated mechanical problems may remain inefficient after local repairs.
A local repair may make sense if:
- The frame and sash remain structurally sound
- Compatible gaskets remain available
- The window can still close securely
- The glazing remains clear and intact
- The internal lining can be opened without major disruption
The specialist may recommend replacement if:
- The timber frame has extensive rot
- The product has been discontinued for many years
- The total repair cost approaches the cost of replacement
- The frame is badly warped
- The homeowner wants better glazing or powered operation
Do Roof Window Seal Repairs Need Approval?
Routine gasket, hinge and draught repairs do not normally require planning permission. Consent may be relevant where original historic materials or window details will be altered.
A contractor should explain if a draught repair develops into a replacement or structural project.
Property owners across West Sussex can check local planning and building control guidance on the West Sussex County Council website.

Frequently Asked Questions About Roof Window Seal and Draught Repairs in West Sussex
How much do roof window seal repairs cost in West Sussex?
Roof window seal repair costs in West Sussex depend on the make, model, number of gaskets required and cause of the draught. A straightforward seal replacement normally costs less than work involving hinges, locks, powered controls, internal linings or missing insulation.
How do I know if my roof window seals need replacing?
Common signs include cold air around the sash, whistling during windy weather, visible gaps, flattened or cracked gaskets and a window that no longer closes evenly. A specialist should also check the hinges, locks and frame insulation before recommending replacement seals.
Why is cold air coming through my roof window?
Cold air may enter through worn seals, a misaligned sash, faulty locks, an open or damaged ventilation flap, gaps in the internal lining or missing insulation around the frame. More than one fault can contribute to the draught.
Can roof window seals be replaced?
Roof window seals can often be replaced where compatible gaskets remain available. The contractor will usually need the window manufacturer, model, size and production code to identify the correct profile.
Can I use a generic draught-proofing strip on a roof window?
Generic draught strips are not always suitable for roof windows. An incorrect profile can stop the sash closing, interfere with drainage or create uneven pressure. Manufacturer-compatible seals are normally preferable.
Why does my roof window whistle when it is windy?
A whistling noise is usually caused by air passing through a narrow gap. The opening may result from a flattened seal, poor sash alignment, weak locking pressure or a gap around the internal lining.
Can poor insulation make a roof window feel draughty?
Yes. Missing or compressed insulation around the fixed frame can create cold spots and air movement. The internal lining may need to be opened so that insulation and air-tightness details can be inspected.
Is moisture around my roof window caused by failed seals?
Moisture may result from an external leak, failed seals or indoor condensation. Condensation is more likely where room humidity is high, the glass is cold or insulation around the frame is missing. The cause should be identified before repairs begin.
How long does roof window seal replacement take?
A straightforward gasket replacement may be completed during one visit. Repairs involving ordered components, sash alignment, powered controls, insulation or internal plasterboard can take longer.
Do roof window seal repairs require scaffolding?
Many sash seal and mechanical repairs can be carried out from inside the property. External access may be required where the work also involves flashing, exterior covers or roofing materials.
Should I repair or replace a draughty roof window?
Repair is often worthwhile where the frame and glazing remain sound and the draught comes from worn seals, poor alignment or missing insulation. Replacement may offer better value where the frame is rotten, several components have failed or compatible seals are unavailable.
Do I need planning permission for roof window seal repairs in West Sussex?
Routine seal, gasket and draught repairs to an existing roof window do not normally require planning permission. Listed buildings and properties in conservation areas may have additional restrictions where original materials or details will change.
