Window Mastic in Petts Wood
Mastic around window and door frames, sills and patio doors for Petts Wood, backed by a 12-month guarantee. Call for a quick quote.
- A bead that does not match the frame
- Hard, cracked sealant around windows
- Damp patches on the reveal after heavy rain
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Don’t use solvent cleaners on the joint
- Make sure the drainage slots aren’t blocked
- Keep paint and stain on wooden frames in good order
- Avoid blasting the frames with a pressure washer
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.

From a single sill to a whole house of windows, the work is priced before anything is done. To get one, phone 0345 464 0079 or send us an email with the number of frames and any access details. If you’re dealing with sealant in the wrong colour for the frame and leaking joints at the ends of sills, we can help, whatever the surface.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.
Each job carries a 12-month guarantee, large or small.

What the job involves on each surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes most of a day for a typical house, less for a few frames and we leave things clean and tidy. In Petts Wood, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive

Advice
Quotes for window mastic in Petts Wood
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
- Working hours on commercial sites
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- The type of property
- How we’d reach the joints
Getting a quote is simple: tell us what needs doing and where and its rough size. A few pictures by email make the job easier to understand.

Window mastic in Petts Wood: local notes
Historic houses like Bromley Palace (about 2.6 miles north-west) are a reminder that the area around Petts Wood has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
As a London address, Petts Wood can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you live in an older home near St Francis Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Petts Wood station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.
