Window mastic for homes and businesses in Elstead
Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. Common call-outs are for a bead that doesn’t match the frame and draughty joints inside around the window, on composite doors, window sills and timber windows & doors.
In a smaller place like Elstead, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
Whatever the size of the job, it’s backed by our 12-month guarantee in Elstead and across Surrey.

Elstead questions
Is Elstead within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Milford (Surrey) station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.
What does window mastic cost?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or email us and let us know what needs doing and where.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can resealing stop a draught around my window?
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?
A handful of frames is a short visit. We confirm the timing with your quote.
Do you have sealant for grey or black windows?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames generally suit brown.
Signs you need window mastic in Elstead
Sills take more water than any other part of a window, 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.
Look out for these signs:
- Black, perished sealant on frames
- Rain getting in at the frame or under the sill
- Gaps where the sill meets the wall
- Hard, cracked sealant around windows
For landlords with property near Milford (Surrey) station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Condensation trapped between the panes
- Broken hinges, locks or handles
- A door that needs adjusting, rehanging or new seals
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before you book.

Keeping the joints in good condition
So the new joints stay in good condition:
- Repaint timber before it’s bare
- Make sure the drainage slots are not blocked
- Use gentle cleaners on frames and sealant
- Don’t paint over the silicone
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
Leaks normally 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
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
For anyone letting property in or around Elstead, several properties can go on one quote. Send us the addresses and the work at each.
Can I do it myself?
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.
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.
Different surfaces, different methods
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal. We use a neutral-cure product.
Frames and glazing around Elstead
Historic houses like Wanborough Manor (about 3.7 miles north-east) are a reminder that the area around Elstead 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. 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.
Managing a site like St James CofE Aided Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St James include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.
