What window mastic looks like in Arborfield
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Winnersh station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around Church of St Bartholomew, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Window mastic for homes and businesses in Arborfield
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. We’re often asked to deal with leaking joints at the ends of sills and mastic that has split away from the wall, across timber windows & doors, window sills and uPVC windows.
Around Arborfield, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
A one-year guarantee comes as standard.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.
When something else is needed
In fairness, there are a few things sealant won’t fix:
- Penetrating damp from a failed cavity tray or render
- Rotten timber, which needs a joiner first
- Faulty window hardware
If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.
Surfaces we seal
- Patio & French doors
- Timber windows & doors
- uPVC windows
- Window sills
- Aluminium frames
- Composite doors
Different surfaces, different methods
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.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.

How the visit works
We bring everything the job needs with us, 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 morning for a couple of windows and a door. Somewhere as small as Arborfield, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- 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.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children

How we quote for window mastic
Jobs vary more than people expect. What affects the quote:

Helping us quote
Before you ask for a quote, have a think about:
- How we’d reach the joints
- Whether it has been sealed before

Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.
When to call us in Arborfield
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Any of these means the joints need attention:
- Water coming in at the bottom corners of a door
- Untidy mastic left by window fitters
- Sealant in the wrong colour for the frame
- Black, perished sealant on frames
If you look after a building such as The Coombes Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- How much experience the applicator has
- How hidden problems are handled
- What insurance they hold
- The length of the guarantee
