Construction mastic for Polton sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What sets the cost
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- How much there is to seal
- The size and state of each joint
- Distance, for remote addresses
- How accessible the joints are
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
Details that help us quote
We can often quote from photos and a few details. Please tell us:
- Access details, including height
- Any specification or named product
- Where the site is, with the postcode
- Whether the building will be occupied during the work
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.
How we handle construction mastic in Polton
We work to the specification and the programme, not to habit. Where the specification names a product, we use it. Joint widths, backing, primers and tooling follow the manufacturer’s guidance so the detail on the drawing is what ends up on site. We work on floor and skirting junctions, internal decorators’ caulk and cladding and panel joints, and what we are called in for most is existing joints on a refurb that need cutting out and resealing and perimeter gaps outside the sealant’s range. Most enquiries from Polton start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
For a site around Polton, we plan the mastic in as few trips as the programme allows. Clear drawings, a programme and photos let us bring the right sealants, primers and backing rod first time.
A 12-month guarantee applies to all our work in Midlothian. If an installation problem shows up, ring 01277 525 020 or email us and we’ll arrange a return visit.

Signs you need construction mastic in Polton
On construction sites, joints normally fail early because of when they were sealed, not what was used. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, and the joint has to be redone.
It’s worth sending us details if you spot any of the following:
- Inconsistent sealant finishes from plot to plot
- Caulk cracking where joints are moving more than expected
- Bath and shower joints scraped during the final clean
- Snag items on joints that need redoing before handover
Further education sites such as Edinburgh College - Midlothian Campus, 2.3 miles north-east of Polton, are extended and refurbished from time to time, with mastic often programmed into the summer break.
What your quote should include
- What level of public liability insurance do they hold?
- Who will actually carry out the work
- How joint depth will be controlled
- Are they CHAS accredited or on Constructionline?
Doing it in-house
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Bathrooms, en suites and washrooms

Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. A kitchen-suitable sealant is used.
From enquiry to sign-off
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work normally takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates.

- We start with the drawings, specification and programme.
- We take off quantities and return a fixed quote.
- We agree with the site team which areas come first.
- Plots or floors are sealed as they’re handed over.
