Window mastic in Beacon Hill, done properly
Over two decades of sealing frames has taught us which products suit which walls. We’re fully insured ARBOMaster approved applicators, and we give a 12-month guarantee on the work. We work on patio & French doors, uPVC windows and aluminium frames, and the jobs we see most are cracked or shrunken mastic around the frame and leaking joints at the ends of sills.
Around Beacon 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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Windows and doors in Beacon 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.
If you let a flat or house near Haslemere station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you live in an older home near Church of St Alban, the joint between an old wall and a newer frame is generally the first place rain gets in.

What happens if it’s left?
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. Where a wall is exposed, as many are in small places like Beacon Hill, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
How the visit works
Before we leave, we go over the finished joints with you. The visit itself usually takes anything from an hour or two to a full day, depending on how many frames there are, depending on the amount of work. For a village or hamlet like Beacon Hill, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Keep pets and children clear of the area while we work
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive

Asking for a quote is easy: tell us what needs doing and where and its rough size. Photos by email help us understand the job, and we’ll take it from there.
Advice
Signs you need window mastic in Beacon Hill
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. If the sealant cannot stretch, it splits.
The most common problems we see are:
- Hard, cracked sealant around windows
- Draughty joints inside around the window
- Gaps left after new windows were fitted
- Cracked sealant at the sill ends
If you look after a building such as Beacon Hill Community Primary School, the mastic around its windows and doors needs looking after like any other building’s.

What the job involves on each surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. We match the colour to the frame.
Aluminium frames
Coated aluminium needs a compatible sealant. Neutral-cure sealant is the safe choice.
