Window mastic in Burghclere
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we’ll tell you. Common call-outs are for rain getting in at the frame or under the sill and cracked internal joints between frame and plaster, on patio & French doors, uPVC windows and composite doors.
Mastic can only go onto a dry, clean joint, so window work in Burghclere is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Every job comes with a 12-month guarantee.

When to call us in Burghclere
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
If you can see any of these, it’s time to have the joints looked at:
- Water coming in at the bottom corners of a door
- Rushed sealant from a window installation
- Black, perished sealant on frames
- Sealant in the wrong colour for the frame
Schools such as Burghclere Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- What product goes in the joint
- What the cure time is
- Are they insured?
- Which colour the sealant will be
What affects the quote in Burghclere
The quote reflects the job in front of us. We look at:

- Mould in or behind the old joints
- The product the joint needs
- How much old sealant there is and how hard it is to remove
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

To make quoting easier, let us know:
- How we’d reach the joints
- Whether it’s a home or a business
- Photos by email, if that’s easy

How the job changes 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.
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
Leave it or put it right?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Around Burghclere, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Burghclere homes and the weather
Historic houses like Highclere Castle (about 1.9 miles south-west) are a reminder that the area around Burghclere has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Newbury station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Homes close to Church of the Ascension include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
