What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a single window, longer for several and we leave things clean and tidy. For a village or hamlet like Beacon Hill, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises

What affects the cost of sand mastic

- Whether there’s mould to deal with
- The size of the job

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

- Where the job is, and your postcode

- How many joints, rooms or windows are involved

Why act early in Beacon Hill
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. Around Beacon Hill, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Hotels need rooms back in use, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Honest limits
In fairness, some problems need a different trade:
- Cracked or broken glass
- Sashes that need overhauling
- Damaged stone surrounds

Surface by surface
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we’ll confirm access.
Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Plan mastic work ahead of painting
- Ask us before painting near the mastic
- Inspect the joints round the windows every year or so
- Avoid patching sand mastic with silicone
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
