Window mastic for homes and businesses in Burkham
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through and quietens the whistle on windy days. If the draught is through the window seals instead, we’ll tell you. We work on composite doors, uPVC windows and window sills, and common reasons people get in touch are cracked internal joints between frame and plaster and cracked sealant at the sill ends.
Homes in small places like Burkham often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Looking after it afterwards
Aftercare is simple:
- Wipe condensation off the frames
- Do not aim a pressure washer at the joints
- Clear any debris from frame drain holes
- Don’t paint over the silicone
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just phone 0345 464 0079 or send us an email.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, 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. We seal onto sound, dry paintwork or timber.
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.

Do you cover smaller places like Burkham?

What should I tell you?

Will new mastic stop draughts?
Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.

Can you get sealant to suit coloured frames?
Yes, in most cases. Tell us the frame colour when you get in touch and we will match it as closely as we can.
Windows and doors in Burkham
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. With historic houses such as Hall Place (about 1.9 miles south) nearby, there’s older building stock in the area around Burkham 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.
Rented homes near Alton 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.

Do you need window mastic in Burkham?
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
Common reasons people contact us include:
- Cracked or shrunken mastic around the frame
- Draughts coming in around windows and doors
- Untidy mastic left by window fitters
- Mastic that’s falling out in pieces
Historic houses such as Hall Place, about 1.9 miles south, show how far back building around Burkham goes, and older homes nearby need a sealant that suits their walls.

- Who does the work, and how experienced they are
- What happens if they find a problem under the old sealant
How it works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes most of a day for a typical house, less for a few frames. In a small place like Burkham, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Mention if the joints have been sealed before
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks
How to get a quote
We quote each job on its own, so the first step is telling us about yours. Just phone 0345 464 0079 or drop us an email with the details and send photos if you have them.

Leave it or put it right?
The work is quick compared with the damage it prevents: the visit takes a few hours for a handful of frames, longer for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. In a small place like Burkham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.
