Knightswood: questions and answers
Do hotels near Knightswood have to close for sealant work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.
Will you take on work at estates like Anniesland Industrial Estate, close to Knightswood?
Yes. Estates, retail parks and business parks around Knightswood, Anniesland Industrial Estate among them, are all within reach. To start, just phone 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Can you take on work for an FM or managing agent?
Yes. FMs, managing agents and landlords are among our regular clients. Tell us how you issue work and we’ll fit in.
Can you handle sealant work across several sites?
Yes. We take on runs of jobs across portfolios as well as single sites, priced site by site or as one programme.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
Is the old sealant taken out first?
Removal of the failed sealant is always part of the job. Laying new silicone on old gives it nothing to grip; the faces are then cleaned and prepared.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Sealant applicators in Knightswood
Most of the buildings we seal stay open while we’re there. Tell us your site hours and access windows and we will plan around them; phasing keeps some washrooms, kitchens or entrances available while others are done. That applies whether the building is an office, a shop, a hotel, a college or a care home. We work on floor and threshold joints, external facade joints and movement joints in walls and floors, and the failures we are asked to look at most are wall and floor joints that have lost their seal and gaps behind commercial kitchen worktops and sinks. Searching for sealant specialists in Knightswood? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Quotes for commercial sealant in Knightswood can come from photos and a joint schedule, or from a walk-round, and the scope is set out in writing.
In Scotland’s cities, commercial premises are packed closely, from stone-fronted offices to shops on the ground floor of tenement blocks. Where a shop sits below tenement flats, work on the frontage or shared parts may involve the property factor.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or email drawings and photos and we will arrange a return visit.

Advice
Honest limits
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Suspect materials that need testing and specialist removal
- Broken glass or blown double-glazed units
- Cracking that needs a structural engineer to look at it
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

Site staff or a sealant specialist?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Keep a record of which joints were resealed and when
- Check the asbestos register before anyone disturbs old sealant in an older building
- Put external and wet-area joints on a regular inspection round
Give fresh sealant time to cure before it’s cleaned, wetted or walked past. That time depends on the product, the temperature and the joint depth, so we confirm it for each area at handover. Leaving the area closed until then keeps the bead neat.
A failed external joint lets water in every time it rains. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Resealing early keeps the problem in the sealant and out of the building.
When to call us in Knightswood
Resealing over the top is a false economy we come across often. Fresh sealant won’t stick to the old bead underneath. By the time it shows, there can be two or three layers to cut out.
Most enquiries start with one or more of the following:
- Layers of sealant, all of them failing
- Window and door perimeter joints that have cracked open
- Untidy joints in a reception, shop floor or lobby
- Movement joints packed with grit and debris
Occupiers with premises at both Anniesland Industrial Estate and Knightswood Shopping Centre could have the sealant at each handled under one quote.

What happens if it’s left?
Spot repairs have their place. Where the remaining sealant is just as old, it tends to fail soon after, and a second visit means paying for access and set-up again. We can price both options so you can decide on the facts. Getting access arranged for a building in Knightswood takes time, so it makes sense to renew every failing joint while it’s in place.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
