Window mastic in Brenzett
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you have cracked or shrunken mastic around the frame and leaking joints at the ends of sills, we can put it right, on uPVC windows, patio & French doors and composite doors alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Brenzett is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
A one-year guarantee comes as standard.

What the job involves on each surface
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.
DIY versus a professional finish
If you do try it yourself, take your time over the 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.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The process
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a handful of frames, longer for a whole house. Somewhere like Brenzett needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.

Brenzett homes and the weather

Looking after it afterwards
So the new joints stay in good condition:
- Wipe condensation off the frames
- Keep drainage slots and sill grooves clear
- Do not aim a pressure washer at the joints
- Wash the frames with mild soapy water
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 ring 0345 464 0079 or drop us an email.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
Why act early in Brenzett
Resealing frames is a short job: it takes a few hours for a handful of frames, longer for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. Where a wall is exposed, as many are in small places like Brenzett, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

What we can’t put right
