Window & door mastic in Grove Park, Greater London
Window mastic across Grove Park and nearby, with old sealant always removed completely.
- Mastic that has split away from the wall
- Cracked sealant at the sill ends
- Damp patches on the reveal after heavy rain
Keeping the joints in good condition
So the new joints stay in good condition:
- Clear any debris from frame drain holes
- Clean frames with a soft cloth and soapy water
- Keep jet washers away from the mastic
- Air rooms to keep condensation down around windows
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
About our window mastic in Grove Park
Homes in Grove Park have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on window sills, uPVC windows and timber windows & doors, and common reasons people get in touch are cracked or shrunken mastic around the frame and cracked sealant at the sill ends.
Many London homes are flats, with windows high above the street. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Grove Park is something to talk through when you book.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.

Signs you need window mastic in Grove Park
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that cannot keep up eventually tears.
If you can see any of these, it’s time to have the joints looked at:
- Damp patches on the reveal after heavy rain
- White mastic on grey or black frames
- Gaps between the frame and the inside reveal
- Whistling draughts around closed windows
Rented homes near Chiswick station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What happens if it’s left?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Grove Park.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

What we do, step by step
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours for a handful of frames, longer for a whole house, including the tidy-up. In Grove Park, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Before we arrive
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive

Grove Park homes and the weather
Historic houses like Chiswick House (about 0.5 miles east) are a reminder that the area around Grove Park 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. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book.
In the older streets around St Paul's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Grove Park is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Can new window sealant be painted?
That depends on the product. Silicone is not paintable, but some hybrid sealants are. Tell us if you are decorating and we will choose accordingly.
What information do you need?

It will if the frame joint is the problem. We check where the draught is before we start.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

How the job changes by surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
