Window mastic in Peasemore, done properly
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and we give a one-year guarantee on the work. We’re often asked to deal with gaps between the frame and the inside reveal and gaps left after new windows were fitted, across patio & French doors, timber windows & doors and uPVC windows.
Homes in small places like Peasemore 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.
Every job comes with a 12-month guarantee, wherever you are in West Berkshire.

Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep timber frames painted
- Avoid blasting the frames with a pressure washer
- Wash the frames with mild soapy water
- Clear any debris from frame drain holes
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.
Questions from Peasemore
What guarantee comes with window mastic in Peasemore?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Can you do window mastic in Peasemore?
Yes, Peasemore is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear quote.
How long should I leave it?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
What does window mastic cost?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or drop us an email with a short description of the job.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Is it OK to seal over old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Can you do the inside joint as well?
Yes. Inside, the joint between frame and plaster is sealed neatly.
Window mastic in Peasemore: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Church of St Barnabas, the joint between an old wall and a newer frame is normally the first place rain gets in.

Common problems we fix in Peasemore
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. That is what backing rod is for.
Common reasons people contact us include:
- A bead that doesn’t match the frame
- Cold air getting in at the frame edge
- Hard, cracked sealant around windows
- Leaking joints at the ends of sills
In and around Peasemore, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- What the quote includes, VAT included or not
- Are they insured?
- Whether all the old sealant comes out first
- How long to leave it before use
What we cannot put right
We will always be straight with you, so here’s what new sealant will not do:
- Condensation trapped between the panes
- A door that needs adjusting, rehanging or new seals
- Penetrating damp from a failed cavity tray or render
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
Where we work in Peasemore

Why act early in Peasemore
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Where a wall is exposed, as many are in small places like Peasemore, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Doing several joints on one visit is usually more efficient than separate visits. You’ll get one clear quote for the whole job.

The process
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. The work generally takes most of a day for a typical house, less for a few frames. For a village or hamlet like Peasemore, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
How to prepare
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before
