Window & door mastic in Boundstone, Surrey
Professional window mastic in and around Boundstone, with old sealant always removed completely and a one-year guarantee.
- Gaps left after new windows were fitted
- A bead that does not match the frame
- Draughty joints inside around the window
Window mastic in Boundstone, done properly
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. If you’re dealing with cracked internal joints between frame and plaster and gaps left after new windows were fitted, we can put it right, on composite doors, uPVC windows and aluminium frames alike.
In a smaller place like Boundstone, some walls face open ground and catch the full force of the weather. That is hard on the mastic around frames and sills.
Each job carries a 12-month guarantee.

Window mastic in Boundstone: local notes
With historic houses such as Farnham Castle (about 2 miles north) nearby, there’s older building stock in the area around Boundstone as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Homes close to St Timothy include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Farnham 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.

What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
How long does it take to reseal the windows on a house?
The work takes a morning for a couple of windows and a door. Access and the amount of old mastic make the biggest difference.

Honest limits
It helps to know what we cannot do:
- Penetrating damp from a failed cavity tray or render
- Condensation trapped between the panes

What we’re called out for in Boundstone
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
The most common problems we see are:
- Old mastic that has gone black or come away
- Draughty joints inside around the window
- Hard, cracked sealant around windows
- Draughts coming in around windows and doors
Schools such as St Peter's CofE Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
Before booking anyone
- Whether all the old sealant comes out first
- Is VAT in the price?
- How the joint is cleaned and prepared
- Are they insured?
Different surfaces, different methods
Composite doors
Front doors take the weather head on. We pay most attention there.
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.
Quotes for window mastic in Boundstone
Call for a quick quote. The main things that affect it are:
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
- How easy the joints are to reach
- Which sealant suits the joint
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- A few pictures by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
- Access, such as stairs, a lift or height
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Leave it or put it right?
Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we will say so. Around Boundstone, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
