Mastic around window and door frames, sills and patio doors for householders, landlords and businesses in Nalderswood. Fully insured, ARBOMaster approved and guaranteed for a year.

Window mastic in Nalderswood, done properly
Around Nalderswood we seal all kinds of frames: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on timber windows & doors, uPVC windows and composite doors, and the jobs we see most are draughty joints inside around the window and cracked sealant at the sill ends.
In a village or hamlet like Nalderswood, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Frames and glazing around Nalderswood
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Salfords station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you look after a building such as Burys Court School, larger buildings have plenty of frames, and the mastic around each one ages.

How the job changes by surface
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
What we can’t put right
A few problems are outside what sealant work can do:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A sash or casement that won’t close properly
- Worn gaskets, brush seals or a door that has dropped
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before booking.

Landlord and commercial work in Nalderswood
In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Common problems we fix in Nalderswood
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, and a gap filled solid can’t flex. That’s what backing rod is for.
It’s worth asking for a quote if you see:
- Draughts coming in around windows and doors
- White mastic on grey or black frames
- Gaps left after new windows were fitted
- Leaking joints at the ends of sills
Homes close to Church of St Bartholomew include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.

What happens if it’s left?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. Where a wall is exposed, as many are in small places like Nalderswood, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

FAQs for Nalderswood
Is Nalderswood within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Salfords station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do you have insurance?
Yes. We are fully insured.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Do you have sealant for grey or black windows?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
