Sand Mastic in Newport-on-Tay
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for homeowners, landlords and businesses in Newport-on-Tay. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps where the frame meets the masonry
- Mastic round period door frames that has failed
How we handle sand mastic in Newport-on-Tay
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. We work on timber door frames, tenement windows and period & listed homes, and common reasons people get in touch are old cement repairs round a window that have failed and cracked mastic round a front door frame.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What happens if it’s left?
New mastic over crumbling mastic will not hold. We remove the loose material first so the new work lasts. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.
Why us?
- Tidy, careful work
- 20+ years of sealant experience
- Anti-fungal sanitary silicone in wet areas
- We are fully insured

Windows and doors in Newport-on-Tay
Newport-on-Tay is close to 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. With historic houses such as Camperdown House (about 5 miles north-west) nearby, there’s older building stock in the area around Newport-on-Tay as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Newport Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Dundee station, any sash windows need sound mastic to keep draughts and rain out.

Newport-on-Tay: your questions answered
Can you help a landlord with a rental near Dundee station?
Yes, we work for letting agents and landlords. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
Does the coastal weather in Newport-on-Tay affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.

Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we are using and why.
What does sand mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long does sand mastic take?
A typical job takes a few hours for a single window, longer for several. We will confirm how long when we quote.
Is the work guaranteed?
You get our 12-month guarantee to all our work.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Have rotten timber repaired before new mastic goes in
- Don’t paint over the new mastic
- Check with your local planning authority if your home is listed
- Avoid patching sand mastic with silicone
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
When something else is needed
Before you book, it’s worth knowing the limits too:
- Putty and glazing repairs
- Sashes that rattle, stick or will not open
- Planning or listed building consent (your local planning authority decides)
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.
Surfaces we seal

For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
The process
Before we leave, we go over the finished joints with you. The visit itself usually takes a few hours per window, depending on the condition of the joints, depending on how much there is to do. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
