Do you work on first-floor windows?

Can you match the sealant to my frames?

It depends on the sealant. Some hybrid sealants can be painted; silicone can’t. Tell us if you’re decorating and we’ll choose accordingly.
About our window mastic in Ash
Around Ash we seal all kinds of frames: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you have a bead that doesn’t match the frame and old mastic that has gone black or come away, we can help, on composite doors, uPVC windows and window sills alike.
Many houses in smaller places like Ash have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
There’s a 12-month guarantee on every job.

What affects the quote in Ash
You will get a clear quote before work begins. It’s based on:
- Which sealant suits the joint
- Whether there’s mould to deal with
- When we can work, for business premises
- The number and length of the joints
Leaving a failed joint usually makes the job bigger, not smaller. If you’re unsure, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- The rough size of the job
- Photos by email, if that’s easy
- How we’d reach the joints

- Faulty window hardware

For landlords and businesses
For anyone letting property in or around Ash, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Keep timber frames painted
- Air rooms to keep condensation down around windows
- Walk round the house once a year and look at the joints
- Don’t use solvent cleaners on the joint
Silicone cannot normally be painted, so mention any painting plans before any work starts. We can use a paintable sealant where that matters.
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.
How the visit works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes anything from an hour or two to a full day, depending on how many frames there are, including the tidy-up. For a job in Ash, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We check each frame and agree which ones need doing.
- 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.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Preparing for the visit
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can

Can I do it myself?
A careful DIYer can reseal a simple joint, 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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Surface by surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so we pay close attention there.
Frames and glazing around Ash
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Wanborough Manor (about 2.7 miles east) nearby, there’s older building stock in the area around Ash 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.
For an older house near a landmark such as Church of St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Walsh CofE Junior School, larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Ash station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
