Window mastic in Weston, done properly
A window frame and the wall around it expand and shrink at different rates. 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. If you have white mastic on grey or black frames and rushed sealant from a window installation, we can help, whatever the surface.
Outdoor sealant needs dry, clean surfaces, so work on frames around Weston is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
We stand behind the work with a 12-month guarantee.

Why deal with it now?
Choosing the product is half the job. Interior caulk and bathroom silicone are not made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. Where a wall is exposed, as many are in small places like Weston, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

What the job involves on each surface
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the sealant goes in between frame and wall and tooled smooth.
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
What happens on the day
At the end, we look at the finished work together and explain the cure time. The work normally takes most of a day for a typical house, less for a few frames, depending on how much there is to do. In a small place like Weston, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive

What window mastic looks like in Weston
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. With historic houses such as Benham Park (about 4.7 miles south-east) nearby, there’s older building stock in the area around Weston 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.
For an older house near a landmark such as St Thomas' Church, the joint between an old wall and a newer frame is generally the first place rain gets in.
Weston is about 6 miles north-west of Newbury, in West Berkshire. Weston gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Paint up to the joint, not over it
- Clean frames with a soft cloth and soapy water
- Look round the frames every year or so
- Air rooms to keep condensation down around windows
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just call 0345 464 0079 or drop us an email.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
What we’re called out for in Weston
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. A sealant that can’t keep up eventually tears.
If you can see any of these, it’s time to have the joints looked at:
- Cracked internal joints between frame and plaster
- Cracked or shrunken mastic around the frame
- Draughts coming in around windows and doors
- Old mastic that has gone black or come away
If you let a flat or house near Kintbury station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Common questions in Weston
Do you cover smaller places like Weston?
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.

Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Do I need to be at home?

Our base is in Crawley, and we work across South East England, London and Scotland.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
How long will my window job take?
The work takes anything from an hour or two to a full day, depending on how many frames there are. Access and the amount of old mastic make the biggest difference.
Do you work on first-floor windows?
Yes, where it’s safe. For high or awkward windows, we will tell you what access is needed.
Do you guarantee window mastic?
Yes. All our work carries a 12-month guarantee, and we’re fully insured.
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 matched to the joint and its conditions, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
