Window mastic for homes and businesses in East Peckham
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. If you are dealing with leaking joints at the ends of sills and black, perished sealant on frames, we can help, whatever the surface.
Around East Peckham, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Surface by surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour suits the frame.
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
Looking after it afterwards
After the cure time, these simple habits help:
- Wipe condensation off the frames
- Keep paint off silicone joints
- Keep drainage slots and sill grooves clear
- Use gentle cleaners on frames and sealant
Most silicone sealants won’t take paint, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Leaks normally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
How it works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of frames, longer for a whole house. For a village or hamlet like East Peckham, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- 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.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know about parking restrictions
- Let us know about stairs, lifts or work at height

What window mastic looks like in East Peckham
With historic houses such as Old Soar Manor (about 4.5 miles north-west) nearby, there’s older building stock in the area around East Peckham as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as East Peckham Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Beltring station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

When it isn’t the sealant
We won’t take on work that will not last, so here’s what sealant cannot put right:
- A frame that has rotted at the joint
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Worn gaskets, brush seals or a door that has dropped
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before you book.

Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Common problems we fix in East Peckham
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
Most people get in touch when they notice something like this:
- Gaps between the frame and the inside reveal
- Draughts coming in around windows and doors
- Rushed sealant from a window installation
- Mastic that has split away from the wall
For an older house near a landmark such as Church of the Holy Trinity, the joint between an old wall and a newer frame is normally the first place rain gets in.
