Sand mastic in Hamilton, done properly
Sand mastic does not last for ever, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We’re often asked to deal with gaps between timber frames and stone or brick and mastic that needs renewing before redecorating, on timber door frames, tenement windows and period & listed homes.
Wind and rain in a Scottish town like Hamilton find any gap around a frame. The windows facing the weather are normally the first to leak.
You are covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Hamilton homes and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
If you live in an older home near Auchingramont Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Earnock High School, its window and door frames need their mastic kept sound, just like a home’s.

Do you need sand mastic in Hamilton?
Timber frames move with the seasons. The movement cracks the mastic little by little.
These are the problems we’re asked about most:
- Mastic that needs renewing before redecorating
- Old cement repairs round a window that have failed
- Gaps between timber frames and stone or brick
- Gaps round a timber door in stone or brick
Rented homes near Hamilton West station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
Questions to ask before booking

What we can’t put right

Your questions about sand mastic in Hamilton
Can you help a landlord with a rental near Hamilton West station?
Yes. We work for landlords and letting agents as well as homeowners. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
What guarantee comes with sand mastic in Hamilton?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Hamilton, along with the rest of our area.
Do you work in Hamilton?
Yes, we do. Our applicators work in Hamilton, and the service is the same as everywhere else.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
What information do you need?
A short description and the location. If we need more, we’ll ask.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Ask the planning authority about consent for listed or conservation-area homes
- Sort the mastic before the decorators arrive
- Clear gutters so water doesn’t pour onto the windows
- Ask a joiner to look at soft timber first
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
For anyone letting property in or around Hamilton, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.
How the job changes by surface
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.
What affects the quote in Hamilton
Jobs vary more than people expect. The main factors:
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- How easy the joints are to reach
- When we can work, for business premises
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll explain what it covers.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Photos by email, if that’s easy
- The type of property
- Whether it has been sealed before
- How many joints, rooms or windows are involved
There’s no standard price list. Instead, we send you a clear quote for your job. To arrange one, send an email to info@mrmastic.co.uk.
The process
The work is kept neat and contained to the area we’re working on, so you can get on with your day. The job generally takes anything from a few hours to a full day, depending on how many windows, and we explain the cure time before we leave. A visit in Hamilton needs three things planned: access, parking and where the work is. Outside work depends on the weather, as sealant needs a dry surface.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
