Construction mastic in Knightswood
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old. After that, the joints are prepared and sealed to the specification. If you have perimeter gaps outside the sealant’s range and missed perimeter joints on a new elevation, we can help, on sanitary and kitchen joints, internal decorators’ caulk and brick and block movement joints alike. Whoever orders the work in Knightswood, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
City-centre sites in Scotland usually mean booked deliveries, tight storage and shared access. Our CSCS-carded applicators work to the site induction, the programme and the sequence of trades.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What else we do in Knightswood
Facades, frames and programmes in Knightswood
Scotland has its own building regulations, and in Knightswood warrants come from the local authority verifier. Our job is to seal to that specification. Knightswood has several hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Further education sites such as Glasgow Clyde College - Anniesland Campus, 1 mile south-east of Knightswood, are extended and refurbished from time to time, with mastic often programmed into the summer break. New wings at hospitals like Gartnavel Royal Hospital, 1.2 miles to the south-east of Knightswood, bring long runs of window and panel joints to seal. Hotels like Leonardo Inn Hotel Glasgow West End, 1.3 miles south-east of Knightswood, rarely close for long, so refurbishment mastic is phased floor by floor.

Around Knightswood
Around Knightswood, our work takes us to commercial buildings near Scotstoun Primary School, Jordanhill College and Lock 27 pub, among other places. Knightswood’s nearest station is Westerton station, roughly 0.8 miles north. Other landmarks nearby include Renfrew Castle (1.8 miles south-west) and Renfrew Museum (2.1 miles south-west).

Why deal with it now?
A quick bead over a damaged joint can get an area past inspection, but it rarely lasts. New sealant laid on old or dirty sealant has nothing to bond to, and the defect comes back after handover. We cut out and redo the joint properly. Scottish city buildings take plenty of rain, so a split or hardened joint lets water into the wall. Renewing them early protects the fabric.
We don’t publish prices, since every building and every scope is different. Call for a quote.

Your questions answered
Who arranges mastic work on a tenement in Knightswood?
Usually the owners agree it together, and a property factor often handles the arrangements. Send details and photographs, and we will quote to whoever is arranging it.
Do you take on work at healthcare sites like Gartnavel Royal Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Can you send site paperwork?
Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.
Cost factors for mastic packages
There’s no standard rate for sealant work, because every site is different. What we look at:
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
- Removal of failed or old sealant
- Distance, for remote addresses
A quote for mastic packages depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
Before you send an enquiry
Good information means a firmer quote. Helpful details to send:
- Where the site is, with the postcode
- What the building is and how it’s used
- Any dates the work must fit around
- Access details, including height
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
Diagnose, treat, sign off
Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Give us the access times and building rules for your premises in Knightswood, so the work can be phased and areas kept in use.
- We price from the drawings, specification and programme you send.
- We return a fixed quote that ties the mastic package to your programme.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- We seal each plot or floor as it’s released to us.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Before we start on site

Advice
What the job involves on each surface
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. We set the depth with backing rod to avoid three-sided adhesion.
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Each joint is prepared, sealed and finished with a neat tooled line.
What we can’t put right
We check first that sealant really is the fix. It won’t put right:
- Rework caused by others damaging completed areas
- Joint design decisions that belong to the architect or engineer
- Approving fire stopping as compliant
Not sure which it is? You can call the office on 01277 525 020 or email us and we’ll tell you honestly before you book.
What we seal
