Mastic sealing in Galashiels
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Doing it in-house
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
About our mastic sealing in Galashiels
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. We work on balcony and threshold joints, external wall and movement joints and communal entrances and stairwells, and the usual reasons a site gets in touch are patchy repairs in mismatched sealant and open joints in brickwork or panels. Whether you call it commercial sealant work, mastic application or joint sealing, in Galashiels it comes down to the same thing: the right product in a properly prepared joint.
Owners with several buildings in a town like Galashiels can group mastic work into one programme. Residents are kept informed through the factor or landlord as work moves between buildings.
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 happens if it’s left?
Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work with less control over timing. If one joint has failed on a building in Galashiels, its neighbours, laid at the same time, may not be far off. One programme for all of them saves time.
A quote for mastic joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Diagnose, treat, sign off
Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Jobs in Galashiels are planned with two things in mind: the forecast for external joints and the building’s hours for internal ones. Photos or drawings let us give a fixed quote and a realistic plan.
- We inspect the joints, building by building, and record what has failed and why.
- We send a fixed quote that sets out the joints, the products and the programme.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Before we start on site
- Explain the parking and delivery arrangements
- Move anything stored against the joints

Cost factors for mastic joints
Quotes vary with the job. Expect it to depend on:
- Specialist products, such as fire-rated or hygienic sealants
- Whether old sealant has to be cut out first
- The site’s rules and procedures
- Quantities, in metres or numbers
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.
What we need to price the job
Good information means a firmer quote. Helpful details to send:
- Drawings or a marked-up plan, if available
- The product your specification calls for
- Anything awkward about access or site hours
- Any dates the work must fit around
To get a fixed quote, call the office on 01277 525 020 or send details through our quote form with the site address and an outline of the work. Our quote form is another easy route.
Maintenance after handover
Problems stay small when the joints are checked regularly. In particular:
- Make it easy for occupiers to report draughts
- Share your contractor requirements early
- Log resealing dates block by block
- Protect low-level joints in entrances
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and gives you a history.
Joints on a building age together so a single failure is a sign to check the rest. Doing them together saves going back again and again.
What we’re called out for in Galashiels
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Regular cleaning wears them further.
Most enquiries start with something like this:
- No planned programme for sealant
- Patchy repairs in mismatched sealant
- The same joint failures repeated across a portfolio
- Worn sealant at communal door frames
With historic buildings such as Peel House (3.8 miles west of Galashiels) in the wider area, owners of older properties around Galashiels should expect mastic to need a product that suits old masonry.
