How the job changes by surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We’ll tell you which suits your home.
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Window mastic for homes and businesses in Chipstead
From a single sill to a whole house of windows, you will get a clear quote before we start. Just phone 0345 464 0079 or drop us an email and tell us how many frames there are and how they’re reached. Common call-outs are for sealant in the wrong colour for the frame and cracked or shrunken mastic around the frame, across aluminium frames, timber windows & doors and window sills.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease usually says who is responsible for the windows, so it’s worth checking before booking.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Should I try it myself first?
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.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Your questions about window mastic in Chipstead
Is parking an issue for window mastic in Chipstead?
Parking in Chipstead, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you cover Chipstead for window mastic?
Yes. Our work covers London and the South East, and Chipstead is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear price.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.
Can you seal the gap between the frame and the plaster indoors?
Yes. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or email us.
Can I paint over the new sealant?
Not usually, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Can I add another job to the visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Leave it or put it right?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Chipstead, the repair is bigger than the sealant job would have been.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep solvents and bleach off the sealant
- Paint up to the joint, not over it
- Clean frames with a soft cloth and soapy water
- Look round the frames every year or so
Silicone can’t generally be painted, so mention any painting plans before we start. We can use a paintable sealant where that matters.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. Resealing closes it.
Window mastic in Chipstead: local notes
Historic houses like Nonsuch Mansion (about 4.5 miles north-west) are a reminder that the area around Chipstead has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Chipstead is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you live in an older home near Church of St Margaret, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Chipstead station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How the visit works
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a few frames, or a day or more for a whole house. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Chipstead. A visitor permit or a nearby bay makes the visit run more smoothly.
- Each frame is looked over and we agree which ones need resealing.
- 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.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises
