Need expansion joint sealing in Newtown?

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Our process

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Several jobs near Newtown can be grouped on one trip. Tell us your site hours and we will plan around them.

  1. We look at the joints, their width and how they’ve failed.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. We strip out the old seal and prepare the faces.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Getting the site ready

  • For older buildings, check the asbestos register before work
  • Have the specification and drawings to hand
  • Explain the parking and delivery arrangements

Advice

Expansion joint sealing in Newtown

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. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. The enquiries we see most involve water getting into the wall through a failed joint and sealant peeling off one face of the joint, on precast concrete panel joints, blockwork control joints and cladding panel joints. Whoever orders the work in Newtown, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Around places the size of Newtown, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Concrete floors and yards in these buildings move and crack like any others.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Common questions from Newtown clients

Would you work within a site like Royal Berkshire Hospital?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you cover business parks and estates near Newtown, such as Suttons Business Park?

Yes. Estates, retail parks and business parks around Newtown, Suttons Business Park among them, are all within reach. To start, just ring 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you hold CHAS accreditation?

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

How long will the joint resealing take?

It normally takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, with phasing where areas must stay open. Cure time before reopening is confirmed on the day.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

When to bring in a specialist

Redoing a failed joint usually costs more than getting it right at the outset, 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.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

How the job changes by surface

Concrete and precast panel joints

Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond.

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.

What sets the cost

Quotes vary with the job. Expect it to depend on:

  • Any access equipment needed
  • How much there is to seal
  • Site requirements such as inductions and permits
  • The product specified

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • Your programme or deadline
  • Asbestos survey details if the building is older
  • Drawings or a marked-up plan, if available
  • A wide shot and a close-up of the area

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Why act early in Newtown

A like-for-like reseal of a joint that keeps splitting rarely lasts. A higher movement class, or a design change by the engineer, may be needed, and we’ll say so before quoting. For buildings in places like Newtown, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why clients in Newtown choose us

  • One contact handling all your sites
  • Fixed quotes based on photos, drawings or a visit
  • CSCS-carded applicators
  • Products installed to the manufacturer’s instructions

Expansion joint sealing around Newtown: what changes locally

At about 37 miles from central London, Newtown is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift. Less than 3 miles from Newtown there are at least three named estates and business parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

For buildings at a park such as Suttons Business Park, which lies north-east of Newtown, brick and panel movement joints are easy to forget until one leaks. Hospital campuses such as Royal Berkshire Hospital, 0.6 miles south-west of Newtown, grow in stages, leaving movement joints wherever new blocks meet old. In a school such as New Town Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Honest limits

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)

Not sure which it is? You can ring 01277 525 020 or send photos by email and we will tell you honestly before you book.
