Need mastic sealing in Heriot?
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
General trades versus a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. 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.
How we handle mastic sealing in Heriot
Managing agents and housing associations typically need paperwork before anyone starts. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. We work on window and door perimeters on blocks, communal kitchens and washrooms and external wall and movement joints, and the usual reasons a site gets in touch are repeated reactive repairs to the same buildings and damaged joints in communal entrances and corridors. Whether you call it commercial sealant work, mastic application or joint sealing, in Heriot it comes down to the same thing: the right product in a properly prepared joint.
Outside mastic in Scotland needs dry joints and the right temperature, so work around Heriot is planned with the forecast. We agree a window with some flexibility.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

What else we do in Heriot
Why it’s worth doing now in Heriot
A bead run over old mastic can look like a repair. It doesn’t bond and typically fails within a short time. Cutting out and resealing properly does it once. For buildings near Heriot, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Why appoint us
- 12 months’ guarantee on every job
- One contact handling all your sites
- Standard and matched colours in many product ranges
- Old sealant cut out, never sealed over
From enquiry to sign-off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. Tell us who will meet us and how to get in at your building near Heriot. That goes into the plan alongside the quote.
- We inspect the joints, building by building, and record what has failed and why.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Before we start on site
- Warn occupants and staff about the work
- Share your working hours and any access restrictions
- Agree which areas must stay open

FAQs: Heriot
Is Heriot off your patch?
No. Small places get the same service as large ones. We work across every Scottish council area. Where we can, we group nearby jobs to make the most of each trip.
What paperwork can you provide for a job in Heriot?
We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
How much does the work cost?
That depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we will send them with the quote.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Leaks from above rather than through a joint
- Glazing that needs replacing
If in doubt, call 01277 525 020 or email drawings and photos and we’ll say what we think.
Surfaces we seal
- External wall and movement joints
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Balcony and threshold joints
Commercial clients in Heriot

How the quote is worked out
These are the things that shape the price:
- Site requirements such as inductions and permits
- The product specified
- Access and working height
- The size and state of each joint
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.
Before you send an enquiry
Whether it’s one area or a whole building, these details speed things up:
- Any specification or named product
- Access details, including height
- Any dates the work must fit around
- Approximate linear metres or a joint schedule
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
