How the job changes by surface
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
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 keeps the clean look.
Window mastic in Fulwell
Homes in Fulwell have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. Common call-outs are for black, perished sealant on frames and cracked internal joints between frame and plaster, on composite doors, window sills and timber windows & doors.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in.
Each job carries a 12-month guarantee, whatever its size.

Fulwell homes and the weather
Historic houses like Strawberry Hill House (about 0.6 miles north-east) are a reminder that the area around Fulwell 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
As a London address, Fulwell can be tricky for parking: let us know about parking bays, permits or a driveway. In the older streets around St Michael's, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.

Advice
When to call us in Fulwell
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. A sealant that cannot keep up eventually tears.
Any of these means the joints need attention:
- Gaps where the sill meets the wall
- Old mastic that has gone black or come away
- Water coming in at the bottom corners of a door
- Mastic that has split away from the wall
If you look after a building such as Stanley Primary School, its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- Whether all the old sealant comes out first
- Whether you can choose the colour
- How the joint is cleaned and prepared
- The length of the guarantee
Should I try it myself first?
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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Common questions in Fulwell
Is Fulwell in your area for window mastic?
Yes. We work across London and the South East, and Fulwell is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
Is parking a problem for a job in Fulwell?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Do you have insurance?
Yes. We’re fully insured, and we can confirm the details when we quote.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Will new mastic stop draughts?
Yes, where the draught is at the frame edge. We check where the draught is before any work starts.
When it isn’t the sealant
To be straight with you, some problems need a different trade:
- Draughts through the window seals rather than the frame
- A sash or casement that won’t close properly
- Damp problems in the wall away from the window
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before booking.
