Window mastic in Chawton
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we’ll tell you. We work on timber windows & doors, patio & French doors and aluminium frames, and common reasons people get in touch are black, perished sealant on frames and untidy mastic left by window fitters.
In a village or hamlet like Chawton, 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Landlords, agents and businesses in Chawton
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Surface by surface
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the new bead is laid against the frame and the wall and tooled smooth.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match keeps the clean look.
Why act early in Chawton
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Where a wall is exposed, as many are in small places like Chawton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Windows and doors in Chawton
With historic houses such as Bentworth Hall (about 2.8 miles west) nearby, there’s older building stock in the area around Chawton as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Chawton Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Alton station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For an older house near a landmark such as Church of St Nicholas, the joint between an old wall and a newer frame is normally the first place rain gets in.

How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from an hour or two to a full day, depending on how many frames there are, and the area is left clean. Somewhere like Chawton needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, 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.
Getting ready for the visit
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can

Common questions in Chawton
Do you cover smaller places like Chawton?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Chawton in your area for window mastic?
Yes, Chawton is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we’re using and why.
Are you fully insured?
Yes. We are fully insured.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Air rooms to keep condensation down around windows
- Keep jet washers away from the mastic
- Repaint timber before it’s bare
- Clear any debris from frame drain holes
Keep the new mastic undisturbed while it cures, for as long as we advise. Don’t point a pressure washer at the joints.
Leaks usually show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
