Window & door mastic in Little Bookham, Surrey
Problem with your window and door frames in Little Bookham? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Hard, cracked sealant around windows
- Mastic that’s falling out in pieces
- Draughty joints inside around the window
Different surfaces, different methods
Aluminium frames
Coated aluminium needs a compatible sealant. Neutral-cure sealant is the safe choice.
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Window mastic in Little Bookham, done properly
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. If you have a bead that doesn’t match the frame and cold air getting in at the frame edge, we can help.
Many houses in smaller places like Little Bookham have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
There’s a 12-month guarantee on every job, large or small.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Wash the frames with mild soapy water
- Avoid blasting the frames with a pressure washer
- Repaint timber before it’s bare
- Make sure the drainage slots aren’t blocked
Most silicone sealants will not take paint, so mention any painting plans before work begins. There are paintable sealants for joints that need it.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Damp problems in the wall away from the window
- A door that needs adjusting, rehanging or new seals
- Soft or decayed wood in the frame

Is Little Bookham in your area for window mastic?

Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can you reach windows above the ground floor?
Yes, where they can be reached safely. Tell us about access when you get in touch so we can plan the job.
Can you quote for more than one area?
Of course. Doing several areas at once is usually more efficient.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Do you have sealant for grey or black windows?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.

How the visit works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take most of a day for a typical house, less for a few frames, and we explain the cure time before we leave. For a job in Little Bookham, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can

Advice
Frames and glazing around Little Bookham
Historic houses like Polesden Lacey (about 1.1 miles south-east) are a reminder that the area around Little Bookham 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. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Bookham station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Homes close to Church of St Lawrence include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Howard of Effingham School, the mastic around its windows and doors needs looking after like any other building’s.

What happens if it’s left?
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. In an older home around Little Bookham, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
