Your questions about window mastic in Newchapel
Is Newchapel within the area you cover?
Yes, Newchapel is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you cover Newchapel for window mastic?
Yes. We work across London and the South East, and Newchapel is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
Can you get sealant to suit coloured frames?
Yes. We can use white, brown, anthracite grey, black or clear.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
Is the new sealant paintable?
That depends on the product. Some hybrid sealants can be painted; silicone can’t. Tell us if you are decorating and we’ll choose accordingly.
Window mastic in Newchapel
Over two decades of sealing frames has taught us which products suit which walls. We’re fully insured ARBOMaster approved applicators, and we give a 12-month guarantee on the work. We work on timber windows & doors, patio & French doors and composite doors, and the jobs we see most are a bead that doesn’t match the frame and black, perished sealant on frames.
Somewhere as small as Newchapel, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
There’s a 12-month guarantee on every job, whatever its size.

- Whether there’s mould to deal with
- Any working-time requirements on site

Asking for a quote
You do not need to know the technical terms. Just tell us:
- The problem you’ve noticed
- If someone has resealed it before

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, phone 0345 464 0079 or drop us an email.
When something else is needed
We’ll always be straight with you, so here’s what sealant cannot fix:
- A frame that has rotted at the joint
- A failed sealed unit that has misted up
- Damp problems in the wall away from the window
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.

Newchapel homes and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Saint Hill Manor (about 4 miles south) are a reminder that the area around Newchapel 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.
Schools such as Imberhorne School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Dormans station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Leave it or put it right?
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. In a small place like Newchapel, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not guesswork. That’s why we ask about the job first.

Common problems we fix in Newchapel
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
It’s worth asking for a quote if you see:
- Damp patches on the reveal after heavy rain
- Cracked or shrunken mastic around the frame
- Rushed sealant from a window installation
- Cracked sealant at the sill ends
Historic houses such as Saint Hill Manor, about 4 miles south, show how far back building around Newchapel goes, and older homes nearby need a sealant that suits their walls.

What we do, step by step
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours for a few frames, or a day or more for a whole house, including the tidy-up. For a village or hamlet like Newchapel, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts

Advice

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Wipe condensation off the frames
- Do not paint over the silicone
- Avoid harsh chemicals near the mastic
- Keep drainage slots and sill grooves clear
Try not to touch the new joint while it cures, following the cure time we give you. Do not point a pressure washer at the joints.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
