Window mastic in Benham Hill
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. If the draught is through the window seals instead, we’ll tell you. We work on aluminium frames, uPVC windows and patio & French doors, and the jobs we see most are a bead that doesn’t match the frame and rushed sealant from a window installation.
In a smaller place like Benham Hill, some walls face open ground and catch the full force of the weather. That is hard on the mastic around frames and sills.
You get a 12-month guarantee, the same in Benham Hill as everywhere else we work.

Signs you need window mastic in Benham Hill
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
It’s worth asking for a quote if you see:
- Cracked sealant at the sill ends
- A bead that does not match the frame
- Gaps left after new windows were fitted
- Cracked internal joints between frame and plaster
Shaw House, about 1.2 miles north-west, is one of the historic houses in the wider area around Benham Hill.
Questions to ask before you book
- Whether they seal over old material or remove it
- What insurance they hold
- When the joint can take water or movement
- The length of the guarantee
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Don’t paint over the silicone
- Air rooms to keep condensation down around windows
- Keep jet washers away from the mastic
- Walk round the house once a year and look at the joints
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
How it works
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. The job generally takes a few hours for a few frames, or a day or more for a whole house. Parking around Benham Hill is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Tell us if parking is tricky
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
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 doesn’t work out, we can still put it right.
What window mastic looks like in Benham Hill
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Shaw House (about 1.2 miles north-west) nearby, there’s older building stock in the area around Benham Hill as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Newbury Racecourse station, renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Fir Tree Primary School and Nursery are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

FAQs for Benham Hill
Can you do window mastic in Benham Hill?
Yes. We work across London and the South East, and Benham Hill is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
Is Benham Hill within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Will new mastic stop draughts?
In many cases. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Does the work come with a guarantee?
Yes. Every job comes with our one-year guarantee, and we’re ARBOMaster approved applicators.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few photos.
Can you match the sealant to my frames?
Yes, in most cases. Mention the frame colour when you ask for a quote and we’ll use the nearest match.

Surface by surface
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it, where a rigid one would crack.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
