Window mastic for homes and businesses in Westwood
Frames and walls don’t move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. Common call-outs are for cracked or shrunken mastic around the frame and untidy mastic left by window fitters, on patio & French doors, window sills and composite doors.
Homes in small places like Westwood 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.
All of our work is guaranteed for twelve months.

DIY versus a professional 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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

Signs you need window mastic in Westwood
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. That is what backing rod is for.
The problems people usually mention when they call include:
- Cold air getting in at the frame edge
- Cracked sealant at the sill ends
- Sealant in the wrong colour for the frame
- Water coming in at the bottom corners of a door
For an older house near a landmark such as Church of St Peter and St Paul, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What window mastic looks like in Westwood
With historic houses such as Acrise Place (about 4.9 miles south) nearby, there’s older building stock in the area around Westwood as well as newer homes. 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. 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 let a flat or house near Bekesbourne station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Questions from Westwood
Will you come out to Westwood?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Bekesbourne station. Can you help?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
When is the sealant fully cured?
Cure times vary by product. Before we leave, we’ll tell you the cure time.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Surface by surface
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.
Landlord and commercial work in Westwood
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together.
How the visit works
On the day, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before 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 Westwood, 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 check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- 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.
- The joint is shaped to shed water and the area tidied.
How to prepare
- For business premises, tell us about site rules or sign-in
- Tell us about any water getting in
- Mention any parking rules near the property
