Different surfaces, different methods

Remedial sealant in Garnethill
Remedial jobs in Garnethill normally fall into a few patterns: over-sealed joints, hidden mould, repeat leaks and split movement joints. Each is stripped back and done again properly. If you’re dealing with thick, messy sealant smeared over tiles and black mould underneath the bead, we can put it right, whatever the surface.
Garnethill is in one of Scotland’s four big cities, where many tenement bathrooms were fitted into rooms that weren’t built for them. Space is tight and ventilation can be poor, which is hard on sealant and grout.
Big or small, it’s backed by our 12-month guarantee in Garnethill and across Glasgow.

Can you strip sealant from an acrylic tray safely?
Yes. We avoid heavy scraping and use the right cleaner for each surface, so the new sealant bonds cleanly.

Yes. Tell us about everything you’d like done and we’ll quote it together.
Why act early in Garnethill
Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. Scottish rain finds any gap around a frame or wall joint, and in Garnethill, damp can spread through stone and plaster before anyone sees it.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

How it works
On the day, we look over the joints with you first. Surfaces next to the work are protected before work begins. Most jobs take a few hours, depending on how many layers have to come out. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Garnethill, it helps to know the floor, the door entry arrangements and the nearest parking.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
What to tell us for a quote

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Bathrooms and kitchens in Garnethill
Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. Mould is another matter: a bathroom that stays damp still turns sealant and grout black. Private landlords in Scotland must be registered and meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Failed sealant around a bath or shower is worth sorting between tenancies.
Schools such as St Aloysius' College are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes. In the older streets around St Aloysius Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Letting a property close to Charing Cross (Glasgow) station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
