How we handle window mastic in Weston
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. If you have cracked sealant at the sill ends and white mastic on grey or black frames, we can put it right.
Somewhere as small as Weston, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
There’s a 12-month guarantee on every job.

- The amount of work
- Whether the work is at height

Frames and glazing around Weston
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Weston Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Church of the Holy Trinity include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Weston questions
Is Weston in your area for window mastic?
Yes. Our work covers London and the South East, and Weston is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.
Do you cover smaller places like Weston?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you get sealant to suit coloured frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
Do you have insurance?
Yes. We’re fully insured.
Can landlords and businesses book you?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we are fully insured.
What do you put in the joint?
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.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Leave it or put it right?
Choosing the product is half the job. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. In a small place like Weston, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear price before work begins.

How it works

Most jobs take anything from an hour or two to a full day, depending on how many frames there are.

Everything for the job comes with us, so a second trip is avoided where possible.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit

Related advice
When to call us in Weston
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
Keep an eye out for any of the following:
- Rain getting in at the frame or under the sill
- Rushed sealant from a window installation
- Hard, cracked sealant around windows
- Cold air getting in at the frame edge
Letting a property close to Baldock station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Questions to ask before booking
- How hidden problems are handled
- Who does the work, and how experienced they are
- The length of the guarantee
- Whether all the old sealant comes out first
Can I do it myself?
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.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
For landlords and businesses
If you manage several properties in or around Weston, several properties can be quoted together. Just tell us the addresses and what each one needs.
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Different surfaces, different methods
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
Composite doors
An exposed front door gets wind-driven rain. We pay most attention there.
