Expansion joint sealing in Dewartown, done properly

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. We will tell you if the edges need repairing before sealing. Most enquiries involve water dripping through deck or ramp joints and expansion joints split through the centre of the bead, across car park decks and ramps, cladding panel joints and precast concrete panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Dewartown is the same: the right product in a properly prepared joint.

Around smaller Scottish places like Dewartown, slabs needing attention are often in agricultural buildings, workshops, schools and hotels. Concrete slabs and yards there take vehicles and weather.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Dewartown: questions and answers

Will you take on work at estates like McSence Business Park, close to Dewartown?

Yes, sites like McSence Business Park are within our area, along with the rest of Dewartown. To start, just call the office on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Is Dewartown off your patch?

No. Places such as Dewartown are covered as much as the big towns. We cover the whole of Scotland. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Is movement joint sealing guaranteed?

The 12-month guarantee applies to the workmanship. If a joint we sealed fails inside the 12 months, let us know.

Will you come and look before quoting?

It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Owners, agents and contractors

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

Why deal with it now?

Doing joint resealing alongside other planned works can save on access. But joints already letting water in shouldn’t wait for a programme, as damage continues meanwhile. Urgent joints now, the rest later, is often the sensible plan. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Resealing early avoids that.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Why us?

  • Specification-led, product-correct work
  • Standard and matched colours in many product ranges
  • A fixed quote before work starts
  • One contact handling all your sites

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What we’re called out for in Dewartown

Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch.

Typical triggers for a call:

  • Weathered movement joint sealant that no longer flexes
  • Previous reseals laid over old sealant
  • Water getting into the wall through a failed joint
  • Joints packed with grit and debris

Across sites such as Mayfield Industrial Estate, which lies west of Dewartown, floor and movement joints can be sealed in phases so units keep working.

What to look for in a quote

  • Can the work be phased to keep areas open?
  • Their approach to joint depth and backing
  • Which product they’ll use, and why it suits the joint
  • How long is the guarantee, and what does it include?

Choosing a commercial sealant contractor

What the job involves on each surface

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement flagging broken arrises before sealing.

Car park decks and ramps

Car park joints are some of the hardest-working joints in any building. A trafficable sealant suited to the movement goes in with bays done in phases so the car park keeps running.

How a job runs

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. Where we can, we combine work around Dewartown with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

What we need from you

  • Move anything stored against the joints
  • Tell us what induction or permit system the site runs
  • For older buildings, check the asbestos register before work

Warehouse floors and decks around Dewartown

The 3 miles around Dewartown take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. The east of Scotland, where Dewartown is, gets less rain than the west. Frost and winter road salt still work into open joints in car parks and yards. Autumn is a sensible time to seal them.

In a school such as Newbattle Community High School, movement joints in brick, block and hall floors tend to be forgotten until they leak. For an estate such as Midlothian Community Hospital, which lies west of Dewartown, the joints in ramps, decks and long building elevations all need attention over time.
