Window & door mastic in Clapton, West Berkshire
Our applicators work in Clapton on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Damp patches on the reveal after heavy rain
- Gaps where the sill meets the wall
- A bead that doesn’t match the frame
When something else is needed
A few problems are outside what sealant work can do:
- A sash or casement that will not close properly
- Worn gaskets, brush seals or a door that has dropped
- Rotten timber, which needs a joiner first
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.

Window mastic in Clapton
From a single sill to a whole house of windows, the work is priced before anything is done. To get one, call 0345 464 0079 or drop us an email with the number of frames and any access details. Common call-outs are for rain getting in at the frame or under the sill and gaps left after new windows were fitted, across aluminium frames, patio & French doors and window sills.
In a village or hamlet like Clapton, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
You get a 12-month guarantee, the same in Clapton as everywhere else we work.

What we do, step by step
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes a morning for a couple of windows and a door. In a small place like Clapton, 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.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed

Advice
How we quote for window mastic
Every job gets its own quote. These are the things that affect it:
- The old material and how stubborn it is
- When we can work, for business premises
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- Access, such as stairs, a lift or height
- Where the property is
- The type of property
- Photos by email, if that is easy
Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand, and we will take it from there.
Frames and glazing around Clapton
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Benham Park (about 3.9 miles south-east) are a reminder that the area around Clapton 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.
For landlords with property near Kintbury station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around Church of St Swithin, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How the job changes by surface
Aluminium frames
Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones are not used, as they can attack some metals. We use a neutral-cure product.
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.

Landlords, agents and businesses in Clapton
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Looking after it afterwards
So the new joints stay in good condition:
- Keep jet washers away from the mastic
- Keep drainage slots and sill grooves clear
- Walk round the house once a year and look at the joints
- Wash the frames with mild soapy water
Keep the new mastic undisturbed while it cures, following the cure time we give you. Do not point a pressure washer at the joints.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
