The process
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes most of a day for a typical house, less for a few frames for a typical job. In a small place like Sheet Hill, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
How to prepare
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky

Advice
About our window mastic in Sheet Hill
If you can feel air around a shut window, the gap is often at the frame. 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 will tell you. If you have a bead that doesn’t match the frame and hard, cracked sealant around windows, we can put it right, whatever the surface.
Around Sheet Hill, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Each job carries a 12-month guarantee, whatever its size.

Do you need window mastic in Sheet Hill?
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
The problems people generally mention when they call include:
- Draughts coming in around windows and doors
- Black, perished sealant on frames
- Mastic that has split away from the wall
- Gaps between the frame and the inside reveal
Rented homes near Borough Green & Wrotham station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before booking
- What the quote includes, VAT included or not
- Are they insured?
- Who does the work, and how experienced they are
- How hidden problems are handled
Why it’s worth doing now in Sheet Hill
Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we’ll tell you. Where a wall is exposed, as many are in small places like Sheet Hill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Why Sheet Hill customers choose us
- Anti-fungal silicone where joints get wet
- White, clear, grey or another colour, product permitting

How we quote for window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Access and height
- The old material and how stubborn it is
- The amount of work
- Which sealant suits the joint
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

To make quoting easier, let us know:
- Whether it has been sealed before
- The problem you’ve noticed

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
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 window mastic looks like in Sheet Hill
With historic houses such as Old Soar Manor (about 1.3 miles east) nearby, there’s older building stock in the area around Sheet 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. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Plaxtol Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Plaxtol Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
