What affects the cost of window mastic
The price is agreed before any work begins. It takes into account:
- When we can work, for business premises
- How many areas need sealing
- Whether there’s mould to deal with
- The type of sealant required
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Window mastic for homes and businesses in Ash Vale
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. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on composite doors, aluminium frames and window sills, and people most often call us about cracked sealant at the sill ends and gaps between the frame and the inside reveal.
Homes around Ash Vale range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or email us.

Common questions in Ash Vale
Do you cover smaller places like Ash Vale?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Ash Vale station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do you work on first-floor windows?
Yes, in most cases. We plan safe access before the job.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Where do you work from?
We work from Crawley. We cover Ash Vale and the rest of Surrey.
Do you have sealant for grey or black windows?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Is it OK to seal over old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Can resealing stop a draught around my window?
If the draught is coming in around the frame, yes. If it’s coming through the window seals, we’ll tell you.
How the job changes by surface
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain can’t run into the wall.
Composite doors
An exposed front door gets wind-driven rain. We pay most attention there.
Looking after it afterwards
So the new joints stay in good condition:
- Keep paint and stain on wooden frames in good order
- Clear any debris from frame drain holes
- Wipe condensation off the frames
- Don’t use solvent cleaners on the joint
Most silicone sealants won’t take paint, so if you’re planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.
What we do, step by step
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. It generally takes most of a day for a typical house, less for a few frames. For a job in Ash Vale, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in
How to get a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we will come back to you with a quote.
Advice
Signs you need window mastic in Ash Vale
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Common reasons people contact us are:
- Cracked sealant at the sill ends
- Gaps left after new windows were fitted
- Rain getting in at the frame or under the sill
- Hard, cracked sealant around windows
Letting a property close to Ash Vale station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- What preparation is included
- Whether all the old sealant comes out first
- Which colour the sealant will be
Why it’s worth doing now in Ash Vale
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. In an older home around Ash Vale, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Combining jobs into one visit generally makes better use of the time than several visits. We will give you a clear price for the lot.
What you get with us
- Full insurance on every job
- Approved under the ARBOMaster scheme
- Old sealant always removed completely
- Domestic, commercial and hotel work

Other services in Ash Vale
What window mastic looks like in Ash Vale
With historic houses such as Wanborough Manor (about 3.6 miles south-east) nearby, there’s older building stock in the area around Ash Vale as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
Schools such as Shawfield Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. In the older streets around St Mary's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward 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.
