Sand mastic in Seafield, done properly
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditional guidance is not to paint over it, so ask us before you decorate. We are often asked to deal with failed mastic on an exposed elevation and gaps between timber frames and stone or brick, on timber door frames, tenement windows and sash and case windows.
In and around a place like Seafield, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

Seafield: your questions answered
Do you cover Seafield for sand mastic?
Yes, Seafield is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
Is Seafield within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What is sand mastic?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and finished to sit neatly against the masonry.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can you replace silicone on a period window with sand mastic?
Often, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply drop us a line at info@mrmastic.co.uk.
How do I get a quote for sand mastic in Seafield?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
What affects the cost of sand mastic
The price is agreed before any work begins. It’s based on:
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- The number and length of the joints
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- Roughly how big the job is
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To arrange one, send an email to info@mrmastic.co.uk.
Do you need sand mastic in Seafield?
Most of it is simply age. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
Any of these means the joints need attention:
- Cement or filler used on old window joints that has cracked
- Draughts and rain around sash boxes
- Gaps round a timber door in stone or brick
- Mastic that needs renewing before redecorating
Letting a property close to West Calder station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.
What to look for in a quote
- How long the guarantee is
- How the joint is cleaned and prepared
- Is the old sealant removed completely?
- How long to leave it before use
Windows and doors in Seafield
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
Schools such as Bathgate Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Howden House, about 3 miles east, is one of the historic houses in the wider area around Seafield, and older homes nearby need a sealant that suits their walls.

What happens on the day
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a single window, longer for several. Outdoor work around Seafield depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we’re working on
- Plan for the work area to be out of bounds to pets and children

Why act early in Seafield
Filling over old, loose mastic doesn’t last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
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 make a difference.

What we cannot put right
A few problems are outside what sealant work can do:

- Putty and glazing repairs
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before booking.
Joints and surfaces we work on
- Brick reveals
- Tenement windows
- Sash and case windows
- Stone surrounds
- Period & listed homes
- Timber door frames
Keeping the joints in good condition
Looking after new joints is easy:
- Check the mastic when you check the paintwork
- Check with your local planning authority if your home is listed
- Plan mastic work ahead of painting
- Keep sills and gutters clear so water drains away
Leave the new mastic unpainted, which is the traditional advice. If you’re redecorating, ask us first.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
