Remedial sealant around Altnaharra
Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. But mould still grows into sealant and grout in a room that doesn’t dry out. In Scotland, private landlords have to meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Tired, leaking sealant is worth putting right before a new tenant moves in.
Around Altnaharra, as everywhere, remedial sealant is only as good as the preparation behind it. Whether the job is in Altnaharra itself or nearby, the right material for each joint matters as much as a neat finish.

About our remedial sealant in Altnaharra
Movement and expansion joints fail when the sealant can’t stretch. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. If you have wide, uneven beads that look worse than the old ones and kitchen joints letting water behind the worktop, we can put it right.
Being further from a city does not change the work: everything old is cut out, the joints are cleaned and dried, and new sealant or grout goes in. We just plan the journey and access beforehand.
Big or small, you get the same one-year guarantee in Altnaharra and across Highland.

What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Movement from fittings that aren’t supported
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before you book.

Why deal with it now?
Stripping out botched sealant adds time to a reseal, but rarely a lot: the work takes a few hours for most joints, depending on how much old sealant has to come out. It’s far less disruption than resealing the same joint again and again. 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.

What happens on the day
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours, depending on how many layers have to come out. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children

How the job changes by surface
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. We remove it all and clean back to sound surfaces before backing and resealing.
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, including the smears and film on surrounding tiles. New sealant needs a fully clean surface.

What else we do in Altnaharra
Can I do it myself?
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 fails, we can still redo it.
