Window mastic for homes and businesses in East Clandon
Homes in East Clandon have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on window sills, patio & French doors and timber windows & doors, and people most often call us about a bead that doesn’t match the frame and draughty joints inside around the window.
Mastic can only go onto a dry, clean joint, so window work in East Clandon is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Big or small, you get the same one-year guarantee.

Questions from East Clandon
Do you cover smaller places like East Clandon?
Yes. East Clandon is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Clandon station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access.
Do you have insurance?
Yes. Full insurance covers our work.
Can you do the inside joint as well?
Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.
When is the sealant fully cured?
Cure times vary by product and the temperature. Before we leave, we’ll tell you the cure time.
Can you reach windows above the ground floor?
Yes, where they can be reached safely. Tell us about access when you get in touch and we will plan for it.

How the job changes by surface
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We will tell you if that’s what we find.
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. If we find rot, we will tell you before going ahead, as that is a job for a joiner.
Window mastic in East Clandon: local notes
Historic houses like Hatchlands Park (about 0.5 miles north-east) are a reminder that the area around East Clandon 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. 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.
Rented homes near Clandon station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as Clandon CofE Aided Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

How the visit works
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes most of a day for a typical house, less for a few frames for a typical job. For a village or hamlet like East Clandon, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, we go round the frames with you and agree the list.
- 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.
Preparing for the visit
- Clear the area around the work
- Let us know about stairs, lifts or work at height
- For business premises, tell us about site rules or sign-in
Getting a quote
Getting a quote is simple: tell us what needs doing and where. Photos by email help us understand the job, and we’ll take it from there.

Looking after it afterwards
Aftercare is simple:
- Repaint timber before it’s bare
- Keep solvents and bleach off the sealant
- Clear any debris from frame drain holes
- Ventilate rooms so frames don’t stay wet inside
A yearly look round the frames is enough. Small splits are simple to catch before they leak.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
When something else is needed
Sealant is not the answer to every problem, and we’ll tell you before we start. It won’t solve:
- Draughts through the window seals rather than the frame
- Damp coming through the wall itself rather than the frame joint
- A sash or casement that won’t close properly
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before booking.

What we are called out for in East Clandon
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. If the sealant cannot stretch, it splits.
The problems people usually mention when they call include:
- Black, perished sealant on frames
- Cracked or shrunken mastic around the frame
- Untidy mastic left by window fitters
- Draughty joints inside around the window
If you live in an older home near Church of St Thomas of Canterbury, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
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.
