- Wind and rain getting in round a sash window
- Mastic worn away on windows facing the weather
- Patchy fillers round a sash window
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Sand mastic in Airth, done properly
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. We work on brick reveals, period & listed homes and sash and case windows, and common reasons people get in touch are patchy fillers round a sash window and mastic dropping out of the joint.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Every job is covered by a 12-month guarantee, wherever you are in Falkirk.

What we cannot put right
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Masonry that needs repairing
- Rotten sashes, sills or window boxes (a joiner’s job)
- Sashes that rattle, stick or won’t open
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before booking.
Joints and surfaces we work on

Frames and glazing around Airth
Airth is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For landlords with property near Alloa station, any sash windows need sound mastic to keep draughts and rain out.
Airth is about 4 miles south of Alloa, in Falkirk. Wherever you are in the FK2 postcode area, we can carry out sand mastic at your property. Our Falkirk coverage runs to 50 places, and Airth is one of them. We also work in Edinburgh, around 23 miles away.

Work for landlords, hotels and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Why deal with it now?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. In an older home around Airth, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
Why book with us
- Old sealant always removed completely
- 4.9 on Google from 180+ five-star reviews
- Domestic, commercial and hotel work

How it works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes anything from a few hours to a full day, depending on how many windows, depending on how much there is to do. Outside jobs in Airth need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children
How to get a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.

Your questions about sand mastic in Airth
Do you cover smaller places like Airth?
Yes. Airth is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Does the coastal weather in Airth affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Can you match the sealant colour?
Usually, yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Are you fully insured?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is sand mastic better than silicone for my windows?
Sand mastic generally suits period timber windows best. Modern frames normally suit a flexible sealant, and we will explain why.
Do I need permission for sand mastic on a listed building?
Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
