Expansion joint sealing in Stud Green

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Expansion joint sealing in Stud Green

Brickwork and blockwork walls have vertical movement joints at intervals that most people only notice when the sealant has gone. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled. If you are dealing with weathered movement joint sealant that no longer flexes and joints where the bead has lost adhesion, we can put it right, on cladding panel joints, brickwork movement joints and car park decks and ramps alike. One point of contact handles commercial sealant work in Stud Green from the first photos to the final walk-round, whether it’s one building or several.

Around smaller places such as Stud Green, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or send photos by email and we’ll arrange a return visit.

Stud Green: questions and answers

Is Stud Green off your patch?

Not at all. Stud Green is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Do you take on work at healthcare sites like St Mark's Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is movement joint sealing guaranteed?

The 12-month guarantee applies to the workmanship. Tell us right away if a joint we sealed gives trouble in that time.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

What’s the difference between an expansion joint and a movement joint?

The general name is movement joint, and expansion joint is one common type. On site, people tend to use them interchangeably.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

Do you hold CHAS accreditation?

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

Quoting for work in Stud Green

A fixed quote reflects the actual work. It takes account of:

  • Access and working height
  • Induction, permit and paperwork requirements
  • Which sealant the job calls for
  • Whether old sealant has to be cut out first

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What to include in your enquiry

The more we know, the firmer the quote. Helpful details to send:

  • The postcode of the building
  • How the joints are reached, and at what height
  • What the building is and how it’s used
  • Your programme or deadline

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or email the details over.

Diagnose, treat, sign off

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. For a building around Stud Green, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Finished joints are checked and backed by our 12-month guarantee.

Before we start on site

  • Make sure the joints can be reached
  • Warn occupants and staff about the work
  • Explain the parking and delivery arrangements

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

Advice

When to call us in Stud Green

Weathering wears down sealant on exposed elevations and decks. UV hardens the surface, and the sealant loses its ability to stretch and opens at the next temperature swing.

Most enquiries start with something like this:

  • Movement joints with split or torn sealant
  • Debris jammed in movement joints
  • Rain penetration at brick or block movement joints
  • Previous reseals laid over old sealant

In a school such as Holyport College, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Before you book anyone

  • Are they CHAS accredited or on Constructionline?
  • Whether their applicators hold CSCS cards
  • How long is the guarantee, and what does it include?
  • Proof of insurance

Our contractor checklist

Looking after the joints

For the best life from the joints:

  • Put movement joints on the planned maintenance inspection round
  • Raise snow-clearing blades over deck joints where possible
  • Note which joints were done, when, and with what
  • Clear dirt from joint lines during routine cleaning

Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file.

An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall. A sound seal keeps the joint working.

Traffic, movement and joints around Stud Green

Less than 3 miles from Stud Green there are at least three named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Stud Green sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints.

At places like Priors Way Industrial Estate, which lies north-east of Stud Green, joints are sealed a section at a time so operations carry on. Estates like Trade Park (to the north-east of Stud Green) combine warehouse slabs, yards and loading bays, all with joints under wheels.

Building owners, agents and FMs in Stud Green

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

We work for building owners and managing agents on everything from one building to a spread of sites around Stud Green. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: 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. That’s why many clients bring in a specialist from the beginning.
