About our expansion joint sealing in Preston
Mastic Doctor has sealed movement joints since 2005, for main contractors, FMs, managing agents and building owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. If you’re dealing with water dripping through deck or ramp joints and rain penetration at brick or block movement joints, we can help, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Preston, that means joint design, primers and backing rod as standard.
For floor or movement joints around smaller places like Preston, we plan to finish in one visit where we can. Send photographs, joint widths and details of the traffic first.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Signs you need expansion joint sealing in Preston
When a bead pulls away from one face, it has lost adhesion. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons.
Site and facilities staff are often the first to spot these:
- Sealant peeling off one face of the joint
- Hardened, cracked sealant on exposed facades
- Layers of sealant in a movement joint
- Damp inside where a wall movement joint has failed
Hospitals like Belhaven Hospital (to the east of Preston) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Diagnose, treat, sign off
Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Where we can, we combine work around Preston with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.
- We look at the joints, their width and how they’ve failed.
- Next, we fix a price and confirm the sealant we propose for the movement.
- The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
What we need from you
- Warn occupants and staff about the work
- Share the asbestos register for older buildings
- Send your site hours and access windows

Questions we are asked in Preston
Is Preston off your patch?
Not at all. Preston is within our area. We work across every Scottish council area. Good photos up front let us bring everything on the first visit.
Does a coastal location like Preston affect which sealant is used?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Can you quote from photographs?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member.
What causes movement joint sealant to fail?
Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. We diagnose which one it is before resealing, because the fix differs.
Floors, slabs and movement joints in Preston
Preston lies within about 3 miles of the sea. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, and edges left open tend to break up faster. Preston is on Scotland’s drier eastern side. Frost and winter road salt still work into open joints in car parks and yards. Sealing them in drier months limits winter damage.
For floors and slabs around Preston, the product is chosen for the traffic and the movement at each joint.

When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- A joint that has to be widened or re-detailed before it can work
- Crumbling edges that would give a new bead nothing sound to grip
- Waterproofing layers buried beneath the sealant

Keeping the joints sound
Problems stay small when the joints are checked regularly. Specifically:
- Keep traffic off new joints until the cure time is up
- Note which joints were done, when, and with what
- Include every elevation and deck joint in periodic inspections
- Act on the first tear or lifting edge rather than waiting
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file, so the next reseal starts with the facts.
A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles and it can affect the structure over time. Resealing early limits the damage.
What happens if it’s left?
Spot repairs can be useful on a tight budget. The remaining sealant is often close to failing too and repeated access costs add up. We can price a patch and a full reseal side by side. Renewing every failing joint on one visit is the sensible approach for a place like Preston. Photos of each area help us quote the whole job.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.
