Window & door mastic in Pound Hill, West Sussex
We cover Pound Hill for mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Draughty joints inside around the window
- Whistling draughts around closed windows
- Cracked sealant at the sill ends
How we handle window mastic in Pound Hill
Frames and walls do not move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on timber windows & doors, patio & French doors and composite doors, and people most often call us about a bead that doesn’t match the frame and draughty joints inside around the window.
Houses in smaller places like Pound Hill can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
There’s a 12-month guarantee on every job, large or small.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
FAQs for Pound Hill
Do older homes in Pound Hill need their sealant replacing?
In most cases, yes, if it hasn’t been done for a while. Sealant is a maintenance item: how long it lasts depends on use, cleaning and exposure.
Is Pound Hill within the area you cover?
Yes, Pound Hill is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
How many windows can you do in a day?
That depends on the number of frames, how they’re reached and the state of the old mastic. We’ll tell you how long your job needs when we quote.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Does the work come with a guarantee?
Yes. All our work carries a 12-month guarantee, and we’re ARBOMaster approved applicators.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
When to call us in Pound Hill
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
The most common problems we see are:
- Water coming in at the bottom corners of a door
- Whistling draughts around closed windows
- Gaps left after new windows were fitted
- Cracked or shrunken mastic around the frame
If you let a flat or house near Three Bridges station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Pound Hill homes and the weather
Historic houses like Gravetye Manor (about 4.6 miles south-east) are a reminder that the area around Pound Hill has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Crawley, which Pound Hill is part of, is one of England’s post-war new towns. With many homes from the post-war decades, replacement windows and doors are common. The mastic around replacement frames ages too, and gaps at sills and frame heads are where water gets in.
For an older house near a landmark such as St Barnabas', the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Pound Hill Infant Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Different surfaces, different methods
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the new bead is laid against the frame and the wall.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.
