About our window mastic in Liss Forest
The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. We are often asked to deal with draughts coming in around windows and doors and cracked internal joints between frame and plaster, on timber windows & doors, window sills and composite doors.
Outdoor sealant needs dry, clean surfaces, so work on frames around Liss Forest is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Our work is backed for twelve months, in Liss Forest and everywhere else we cover.

Windows and doors in Liss Forest
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around St Saviour's, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Liss station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

The process
Before we leave, we go over the finished joints with you. The work normally takes a few hours for a few frames, or a day or more for a whole house, depending on the size of the job. Somewhere as small as Liss Forest, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit

Advice
Liss Forest: your questions answered
Can you do window mastic in Liss Forest?
Yes, Liss Forest is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
I let a flat near Liss station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. You can phone 0345 464 0079 or email us with the details for a clear quote.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can resealing stop a draught around my window?
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.
Where are you based?
Mr Mastic is based in Crawley. We cover Liss Forest and the rest of Hampshire, along with the rest of our area.
Is the work guaranteed?
Yes. Our one-year guarantee covers every job.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Why act early in Liss Forest
A quick bead over the top of old mastic looks like an easy fix, but it won’t grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. Older cottages and farmhouses around Liss Forest can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Landlord and commercial work in Liss Forest
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Common problems we fix in Liss Forest
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
Keep an eye out for any of the following:
- Cracked sealant at the sill ends
- Black, perished sealant on frames
- Rain getting in at the frame or under the sill
- Mastic that has split away from the wall
For site and facilities teams at buildings such as Liss Infant School, its window and door frames need their mastic kept sound, just like a home’s.
