Window mastic in Bagnor, done properly
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. We work on aluminium frames, patio & French doors and window sills, and the jobs we see most are water coming in at the bottom corners of a door and untidy mastic left by window fitters.
In a village or hamlet like Bagnor, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Big or small, it’s backed by our 12-month guarantee.

Bagnor: your questions answered
Is Bagnor in your area for window mastic?
Yes. Our work covers London and the South East, and Bagnor is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
Do you work for landlords with property near Newbury station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Are you fully insured?
Yes. We’re fully insured.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Do you work on first-floor windows?
Yes, where they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
How long will my window job take?
The work takes a morning for a couple of windows and a door. Access and how stubborn the old mastic is affect the time most.
Surface by surface
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the sealant goes in between frame and wall.
Composite doors
An exposed front door gets wind-driven rain. We pay most attention there.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Frames and glazing around Bagnor
With historic houses such as Benham Park (about 0.8 miles west) nearby, there’s older building stock in the area around Bagnor 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Newbury station change hands often, and 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 Parish Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Bagnor is about 1 mile north-west of Newbury, in West Berkshire.

Common problems we fix in Bagnor
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that cannot keep up eventually tears.
The problems people normally mention when they call are:
- Cold air getting in at the frame edge
- Gaps where the sill meets the wall
- Mastic that has split away from the wall
- Mastic that is falling out in pieces
Schools such as Robert Sandilands Primary School and Nursery are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

The process
The work is kept neat and contained to the area we are working on. The job generally takes a few hours for a handful of frames, longer for a whole house, and we tell you how long to leave it before we go. In a small place like Bagnor, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Before we arrive
- Tell us about any water getting in
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work

Advice
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Make sure the drainage slots aren’t blocked
- Paint up to the joint, not over it
- Avoid harsh chemicals near the mastic
- Avoid blasting the frames with a pressure washer
A yearly look round the frames is enough. Small splits are simple to catch before they leak.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
