Expansion joint sealing in Midlem, done properly
Joint design counts for as much as the sealant itself. The joint has to be wide enough for the expected movement and the sealant’s movement capability, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. We work on brickwork movement joints, blockwork control joints and precast concrete panel joints, and the usual reasons a site gets in touch are rain penetration at brick or block movement joints and new sealant over old, now failing. Searching for sealant specialists in Midlem? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
For outside joints near Midlem, the Scottish weather sets the timetable: dry faces and the right temperature are essential, so dates have some give. Inside slabs aren’t affected and can be scheduled around the occupier.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to bring in a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Quoting for work in Midlem
Quotes vary with the job. Expect it to depend on:
- Removal of failed or old sealant
- The product specified
- The site’s rules and procedures
- Quantities, in metres or numbers
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.
Sending details for a quote
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Whether the building will be occupied during the work
- Photos of the joints, close up and from further back
- The asbestos register, for older buildings
- Specification clauses that apply
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to give us a call on 01277 525 020 or email a schedule or drawings.
What happens if it’s left?
Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Resealing early avoids that.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Midlem: questions and answers
Can you work on a hospital site such as Dingleton Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does a site in Midlem have to shut while its joints are sealed?
Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we’ll plan from there.
Can you work while the building is occupied?
In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
What guarantee do you give on joint sealing?
Each job is backed by a 12-month guarantee on the workmanship. The guarantee covers how we sealed, not damage caused afterwards.
What’s the quickest route to a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
After the work
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Plan racking layouts so feet don’t land on a joint
- Keep product details with the building records for the next reseal
- Inspect movement joints alongside other routine building checks
- Treat a small split as a warning, not a cosmetic issue
Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it and decks and floors suffer most. A routine sweep is the simplest protection.
Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort. We can suggest an order, worst joints first.

The east of Scotland, where Midlem is, gets less rain than the west. Frost and winter road salt still work into open joints in car parks and yards. Sealing them in drier months limits winter damage.
