Sand mastic for homes and businesses in Murston
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. If you’re dealing with crumbling sand mastic round a window and mastic worn away on windows facing the weather, we can help, whatever the surface.
Many houses in smaller places like Murston have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Windows and doors in Murston
Murston is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Sunny Bank Primary School, the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Sittingbourne station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. Homes close to Church of All Saints include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.

Keeping the joints in good condition
Aftercare is simple:
- Find out about consent before window work on a listed home
- Look over the window mastic once a year
- Have rotten timber repaired before new mastic goes in
- Avoid patching sand mastic with silicone
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.

How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take anything from a few hours to a full day, depending on how many windows. A visit to Murston is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Mention any parking rules near the property
- Mention any tricky access
- For business premises, tell us about site rules or sign-in

Other services in Murston
Why deal with it now?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and finishes neatly against the masonry. In an older home around Murston, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Doing several joints on one visit is usually more efficient than separate visits. We’ll give you a clear price for the lot.
Why book with us
- We never seal over old sealant
- Every job guaranteed for a year
- Anti-fungal sanitary silicone in wet areas
- We leave the area clean and tidy
See our cost guide and our reviews.
Should I try it myself first?
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 does not work out, we can still put it right.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
FAQs for Murston
Can you help a landlord with a rental near Sittingbourne station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Does the coastal weather in Murston affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is the work guaranteed?
All our work has a 12-month guarantee.
How long will you be here?
Typically it takes a few hours per window, depending on the condition of the joints. Larger jobs naturally take longer, and we will tell you how long to expect.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages to suit the site.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
