Construction mastic in Gladsmuir, done properly
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 joints perform as the designer intended. Site teams most often ask us about a long mastic snag list close to completion and oversized or tapered gaps around new frames, on window and door perimeters, floor and skirting junctions and internal decorators’ caulk. A specialist sealant contractor works differently from a general builder: on jobs in Gladsmuir, preparation and product choice get the time they need.
For a site around Gladsmuir, 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.
Work we carry out in East Lothian comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or email a schedule or drawings and we will come back to it.

Should maintenance staff do it?
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Why it’s worth doing now in Gladsmuir
When a package runs over budget, downgrading the product is a common first thought. The saving is small next to the cost of callbacks and defects, especially externally. Where an alternative is genuinely suitable, we will say so. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Gladsmuir, a repair visit takes planning, so it’s better to act early.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It won’t put right:
- Rework caused by others damaging completed areas
- Deciding which fire-stopping product a penetration needs
- Oversized gaps that need packing or adjustment by others
Not sure which it is? You can call 01277 525 020 or send photos by email and we will tell you honestly before you book.
Surfaces we seal
- Floor and skirting junctions
- Cladding and panel joints
- Sanitary and kitchen joints
- Internal decorators’ caulk
- Window and door perimeters
- Brick and block movement joints
Diagnose, treat, sign off
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. For a building near Gladsmuir, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- Final snagging is completed and the 12-month guarantee applies.
What we need from you
- Confirm the product named in the specification
- Send your site hours and access windows
- Explain the parking and delivery arrangements

Common problems we fix in Gladsmuir
On construction sites, joints usually 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.
Most enquiries start with one or more of the following:
- Window and door perimeters that won’t pass inspection
- Bath and shower joints scraped during the final clean
- New external sealant already peeling away
- Existing joints on a refurb that need cutting out and resealing
Historic houses such as Gosford House, 3.3 miles north of Gladsmuir, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Common questions from Gladsmuir clients
Is Gladsmuir too small for you to travel to?
No. Small places get the same service as large ones. We work across every Scottish council area. We plan jobs in smaller places so return trips are kept to a minimum.
Is Macmerry Industrial Estate, near Gladsmuir, within your area?
Yes, sites like Macmerry Industrial Estate are within our area, along with the rest of Gladsmuir. To start, just speak to us on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.
Do your applicators hold CSCS cards?
We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. Public liability insurance of five million pounds is in place too.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do you install fire-rated sealant as part of a package?
We install fire-rated sealant where it is the specified product. We’ll flag if the detail needs a different product.
What happens if the weather stops external sealing?
Conditions have to suit the product before external work starts. Wet or cold joints cause adhesion problems so it’s better to wait.
Maintenance after handover
Regular inspection catches problems early. In particular:
- Brief the final clean team to avoid blades near sealant
- Ask for joint and product checks before the package is urgent
- Put any product change through the designer first
- Note which sealant went where at handover
The package carries our 12-month guarantee for workmanship. The guarantee covers how we sealed, not later damage by other trades, so protecting sealed areas matters.
Sanitary joints that fail early become defects soon after occupation. Leaks behind showers and basins damage finishes and floors, leaving the remedial work to the contractor. Getting the product and preparation right first time avoids that.
Sites and facades in and around Gladsmuir
With the shore within about 3 miles, Gladsmuir counts as a coastal location. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. Projects in Gladsmuir follow Scotland’s building regulations, with the local authority acting as verifier. The mastic follows the specification that goes with the warrant.
On a healthcare site such as East Lothian Community Hospital, which lies east of Gladsmuir, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Units on estates such as Macmerry Industrial Estate (1.2 miles west of Gladsmuir) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
