What affects the quote in Langholm
There’s no set price list, because jobs vary so much. The quote depends on:
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
- Any mould that needs treating
- The size of the job
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

About our new build mastic in Langholm
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that is reasonable, but a seal that is letting water through needs doing now. If you are dealing with gaps behind new kitchen upstands and shower seals failing in the first year or two, we can put it right.
Work in a place like Langholm is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
The work is covered for a year after we finish. If anything isn’t right with it, email us at info@mrmastic.co.uk.

In and around Langholm, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. Whether the job is in Langholm itself or nearby, the right material for each joint matters as much as a neat finish.

What happens if it’s left?
DIY kits don’t solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please drop us a line at info@mrmastic.co.uk and we’ll talk you through it.

Related advice
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Your questions about new build mastic in Langholm
Do you cover Langholm for new build mastic?
Yes, Langholm is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear quote.
Is Langholm within the area you cover?
Yes. Langholm is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Do you work through snagging lists?
Yes. Send it with pictures and we will quote for the sealant items. If something is not sealant, we will say so.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply email us at info@mrmastic.co.uk.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
When it isn’t the sealant
In fairness, there are a few things sealant will not fix:
- Leaking fittings rather than failed sealant
- Cracked trays, tiles or worktops
- Baths and trays that move too much for sealant to cope with
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.

What the job involves on each surface
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and prime where the product needs it.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
