Window & door mastic in Botley, Buckinghamshire
We cover Botley for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Whistling draughts around closed windows
- Gaps between the frame and the inside reveal
- Water coming in at the bottom corners of a door
Why deal with it now?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. In a small place like Botley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.

Windows and doors in Botley
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Chenies Manor House (about 3.1 miles south-east) nearby, there’s older building stock in the area around Botley 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.
Homes close to St George's Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Ley Hill School, the mastic around its windows and doors needs looking after like any other building’s.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Different surfaces, different methods
Composite doors
A composite door usually sits in a plastic outer frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.
How the visit works
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for a handful of frames, longer for a whole house. In a small place like Botley, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height

Do you need window mastic in Botley?
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
The problems people generally mention when they call are:
- Black, perished sealant on frames
- Damp patches on the reveal after heavy rain
- Gaps between the frame and the inside reveal
- Rushed sealant from a window installation
For landlords with property near Amersham station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before booking
- Which colour the sealant will be
- How hidden problems are handled
- The length of the guarantee
- How long to leave it before use
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Keep jet washers away from the mastic
- Look round the frames every year or so
- Keep drainage slots and sill grooves clear
- Keep solvents and bleach off the sealant
Silicone cannot usually be painted, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
