- Draughts and rain around sash boxes
- Gaps between timber frames and stone or brick
- Mastic round period door frames that has failed
- A silicone bead on a sash window that spoils the look
Managing a site like King Offa Primary Academy? Then the mastic around its windows and doors needs looking after like any other building’s.

How we handle sand mastic in Bexhill-on-Sea
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it and tidies the surround. If you are dealing with weathered mastic on the most exposed windows and gaps between timber frames and stone or brick, we can help, on tenement windows, sash and case windows and period & listed homes alike.
Bexhill-on-Sea mixes older streets, where windows have often been replaced, with newer estates fitted with uPVC. In every case, the joint between frame and wall is what keeps water out.
Your job is guaranteed for a year, as with all our work.

What else we do in Bexhill-on-Sea
What happens on the day
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours per window, depending on the condition of the joints. Parking in a town like Bexhill-on-Sea is generally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules

When something else is needed
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Planning or listed building consent (your local planning authority decides)
- Putty and glazing repairs
- Masonry that needs repairing
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
Surfaces we seal
- Period & listed homes
- Stone surrounds
- Sash and case windows
- Brick reveals
- Tenement windows
- Timber door frames
Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What affects the cost of sand mastic
Your quote is based on your job. We look at:
- The type of sealant required
- Any mould that needs treating
- The number of rooms or windows
- The size of the job
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
When you call or email, these details help:
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- A few pictures by email, if you can
- Access, such as stairs, a lift or height
Every job is quoted individually, so start by telling us what you need. Simply call 0345 464 0079 or drop us an email and describe the job and send pictures if you have them.
Frames and glazing around Bexhill-on-Sea
Bexhill-on-Sea is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Bexhill station, any sash windows need sound mastic to keep draughts and rain out.

Why it’s worth doing now in Bexhill-on-Sea
New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new work lasts. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and they’re far easier to fix early.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
