Window mastic in Sarisbury Green
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. If you have cracked internal joints between frame and plaster and whistling draughts around closed windows, we can help.
Around Sarisbury Green, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows.
You get a 12-month guarantee, the same in Sarisbury Green as everywhere else we work.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Look round the frames every year or so
- Avoid harsh chemicals near the mastic
- Keep paint and stain on wooden frames in good order
- Do not aim a pressure washer at the joints
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
Surface by 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.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
What happens if it’s left?
The work is quick compared with the damage it prevents: the visit takes a few hours for a few frames, or a day or more for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. In a smaller place like Sarisbury Green, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.

The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of frames, longer for a whole house. For a job in Sarisbury Green, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks
- On commercial sites, let us know about site rules

When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Condensation trapped between the panes
- Damp coming through the wall itself rather than the frame joint
- A sash or casement that won’t close properly
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before booking.

Sarisbury Green homes and the weather
Sarisbury Green is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. 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 look after a building such as Sarisbury Infant School, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Swanwick station? Then renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to Church of St Paul include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Sarisbury Green: your questions answered
Is window mastic in a coastal place like Sarisbury Green any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
I let a flat near Swanwick station. Can you help?
Yes. We work for letting agents and landlords as well as householders. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Does the work come with a guarantee?
Yes. Every job comes with our 12-month guarantee, and we’re ARBOMaster approved applicators.
What do you need from me for a quote?

Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
