Construction mastic near Kelso
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Different surfaces, different methods
External facade and movement joints
External movement joints often need primer, depending on the substrate. Primer goes on where the sealant maker calls for it and work only when conditions suit.
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification, with backing rod in deeper gaps.
How we handle construction mastic in Kelso
Mastic follows everyone else, which means it absorbs every delay upstream. The sequence is set with the site team and updated as plots or floors are handed over and we don’t seal before other trades have finished in an area. Sealing too early only means coming back once others have damaged it. The enquiries we see most involve internal caulk splitting as the building dries out and mastic snags holding up handover, across internal decorators’ caulk, cladding and panel joints and sanitary and kitchen joints. Looking for mastic applicators who cover Kelso? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
For a site around Kelso, we plan the mastic in as few trips as the programme allows. Send drawings, photos and the programme so everything needed arrives on the first day.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Honest limits
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Deciding which fire-stopping product a penetration needs
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Designing joint widths or choosing the specification (that sits with the designer)
If in doubt, give us a call on 01277 525 020 or email us and we will say what we think before you book.
Surfaces we seal
- Floor and skirting junctions
- Window and door perimeters
- Internal decorators’ caulk
- Cladding and panel joints
- Brick and block movement joints
- Sanitary and kitchen joints
Construction mastic around Kelso: points for this area
Kelso has a number of hotels close by, all within 2 miles. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight. Projects in Kelso follow Scotland’s building regulations, with the local authority acting as verifier. The mastic package follows the approved specification.
Units on estates such as Rosewood Industrial Estate, less than half a mile to the east of Kelso, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Projects at schools like Kelso High School work to term dates, so mastic is programmed tightly.

From enquiry to sign-off
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off.

- First we take quantities off the drawings and read through the specification.
- A fixed quote sets out the scope, the products and the sequence.
- 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.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.

What else we do in Kelso
FAQs: Kelso
Do you cover business parks and estates near Kelso, such as Rosewood Industrial Estate?
Yes. Estates, retail parks and business parks around Kelso, Rosewood Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Would you work within a site like Kelso Hospital?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Is the mastic package guaranteed?
Each package is signed off with a 12-month workmanship guarantee. The guarantee covers our work, not later damage by other trades.
Do you offer coloured sealant?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How many days will you need on site?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
Keeping the joints sound
For the best life from the joints:
- Note which sealant went where at handover
- Brief following trades on areas that have been sealed
- Ask for joint and product checks before the package is urgent
- Flag uneven or tapered frame gaps early
Our 12-month guarantee covers the workmanship from sign-off. The guarantee covers how we sealed, not later damage by other trades.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors. Proper preparation, with the right silicone first time, keeps it off the defects list.
Leave it or put it right?
When a package runs over budget, downgrading the product is a common first thought. A failed joint in the defects period costs far more than the product difference. Where an alternative is genuinely suitable, we’ll say so. Around smaller places like Kelso, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Resealing early avoids that.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
