Windows and doors in Middleton
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Longparish Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of St Nicholas, the joint between an old wall and a newer frame is usually the first place rain gets in. If you let a flat or house near Whitchurch (Hampshire) station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Window mastic in Middleton
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. If you have cracked or shrunken mastic around the frame and black, perished sealant on frames, we can put it right, on patio & French doors, window sills and uPVC windows alike.
Homes in small places like Middleton often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
You get a one-year guarantee, the same in Middleton as everywhere else we work.

Why deal with it now?
Choosing the product is half the job. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Where a wall is exposed, as many are in small places like Middleton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote.

When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Draughts through the window seals rather than the frame
- Condensation trapped between the panes
- Soft or decayed wood in the frame
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before you book.

What we do, step by step
There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes a morning for a couple of windows and a door. In a small place like Middleton, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We tool the joint so water runs off, then clear up.
How to prepare
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep jet washers away from the mastic
- Keep paint off silicone joints
- Do not use solvent cleaners on the joint
- Air rooms to keep condensation down around windows
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
Questions from Middleton
Will you come out to Middleton?
Yes, Middleton is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Middleton for window mastic?
Yes. We work across London and the South East, and Middleton is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Does the work come with a guarantee?
Yes. All our work carries a 12-month guarantee, and we’re ARBOMaster approved applicators.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Middleton, along with the rest of our area.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can you seal the gap between the frame and the plaster indoors?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.

What the job involves on each surface
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
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.
