Window mastic in Highams Park, done properly
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. We’re often asked to deal with untidy mastic left by window fitters and gaps where the sill meets the wall, on patio & French doors, window sills and timber windows & doors.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, letting in draughts and water.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What the job involves on each surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.

Frames and glazing around Highams Park
In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking. With historic houses such as Bruce Castle (about 2.6 miles west) nearby, there’s older building stock in the area around Highams Park as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For an older house near a landmark such as St John's, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Highams Park station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For site and facilities teams at buildings such as South Chingford Foundation School, its window and door frames need their mastic kept sound, just like a home’s.

Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Can you seal the gap between the frame and the plaster indoors?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Can I add another job to the visit?
Yes, we can. More than one area can go on one quote.
Can you get sealant to suit coloured frames?
Generally, yes. Tell us the frame colour when you get in touch and we will use the nearest match.

There is not much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes anything from an hour or two to a full day, depending on how many frames there are, including the tidy-up. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Keep paint off silicone joints
- Don’t use solvent cleaners on the joint
- Look round the frames every year or so
- Keep paint and stain on wooden frames in good order
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just phone 0345 464 0079 or email us.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
