Window & door mastic in Peckham Bush, Kent
Window and door frames in Peckham Bush need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Cold air getting in at the frame edge
- Cracked internal joints between frame and plaster
- Sealant in the wrong colour for the frame
Window mastic in Peckham Bush, done properly
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you have water coming in at the bottom corners of a door and untidy mastic left by window fitters, we can put it right, on window sills, uPVC windows and aluminium frames alike.
In a village or hamlet like Peckham Bush, 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.
Each job carries a 12-month guarantee, large or small.

Peckham Bush homes and the weather
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Old Soar Manor (about 3.8 miles north-west) are a reminder that the area around Peckham Bush 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 is traditional sand mastic.
Rented homes near Yalding station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Homes close to Church of the Holy Trinity include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a handful of frames, longer for a whole house. In a small place like Peckham Bush, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed

How we quote for window mastic
Jobs vary more than people expect. The main factors:
- The number of rooms or windows
- The old material and how stubborn it is
- Whether the work is at height
- Which sealant suits the joint
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
There’s no need for technical detail. Just tell us:
- Roughly how big the job is
- What’s wrong with the joints now
- Whether it has been sealed before
- The type of property
We quote each job on its own, so start by telling us what you need. Simply call 0345 464 0079 or email us and describe the job.
How the job changes by surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.

What we’re called out for in Peckham Bush
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
The most common problems we see are:
- Water coming in at the bottom corners of a door
- Old mastic that has gone black or come away
- Gaps where the sill meets the wall
- Gaps between the frame and the inside reveal
If you look after a building such as East Peckham Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Leave it or put it right?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Around Peckham Bush, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Why us?
- White, clear, grey or coloured to suit, where the product allows
- We never seal over old sealant
- Colour agreed with you before any work starts
- Anti-fungal sanitary silicone in wet areas
