Expansion joint sealing for commercial buildings in Wargrave

Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled. If you’re dealing with new sealant over old, now failing and debris jammed in 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 Wargrave, that means joint design, primers and backing rod as standard.

Work in a smaller place like Wargrave is normally one building at a time, so we gather photos and measurements first. Getting widths, depths and traffic details up front means one visit, not two.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Slabs, ramps and loading bays in Wargrave

At about 33 miles from central London, Wargrave is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds, and their floor joints take forklift and pallet-truck traffic all day. Wargrave sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, while winter salting gets into any joint left open.

In a school such as Robert Piggott CofE Infant School, movement joints in brick, block and hall floors tend to be forgotten until they leak. For estates staff at a university like University of Reading, 2.6 miles to the west of Wargrave, building and paving joints are part of the planned maintenance list.

Building owners, agents and FMs in Wargrave

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

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Wargrave. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Our process

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. Several jobs near Wargrave can be grouped on one trip. Tell us your site hours and we will plan around them.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. The failed seal is removed and both faces are cleaned until sound and dry, 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. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. Finished joints are checked and backed by our 12-month guarantee.

What we need from you

  • Tell us what induction or permit system the site runs
  • Warn occupants and staff about the work
  • Explain the parking and delivery arrangements

Wargrave: questions and answers

Is hospital work, at somewhere like St Mark's Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Is Castle End Business Park, near Wargrave, within your area?

Yes. Our area takes in Wargrave and its surroundings, with estates and business parks such as Castle End Business Park included. To start, just call the office on 01277 525 020 or email us with the unit, the joints involved and your access times.

How do we ask for a quote?

The quote form is the simplest route, though you can also ring 01277 525 020 or use the quote form. Include photos or drawings if you have them.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Do you cover Wargrave?

Yes. Wargrave falls within our area, and the simplest way to start is to ring 01277 525 020 or email a schedule or drawings.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Quoting for work in Wargrave

Each job is priced on its own details. The main factors are:

  • The size and state of each joint
  • Whether the work must be split into stages
  • Access and working height
  • Specialist products, such as fire-rated or hygienic sealants

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 we need to price the job

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • The site address and postcode
  • Approximate linear metres or a joint schedule
  • Anything awkward about access or site hours
  • When you need the work done

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or email drawings and photos if you’d rather talk the job through.

What we can’t put right

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • A joint that has to be widened or re-detailed before it can work
  • Cracking or settlement that calls for an engineer’s assessment
  • Concrete or masonry repairs along the arrises

If in doubt, speak to us on 01277 525 020 or send details through our quote form and we will say what we think.

Signs you need expansion joint sealing in Wargrave

Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. Movement capability is set out in BS EN ISO 11600.

Look out for the following:

  • Damp inside where a wall movement joint has failed
  • Expansion joints split through the centre of the bead
  • New sealant over old, now failing
  • Water dripping through deck or ramp joints

Office parks like Castle End Business Park, 1.3 miles south-east of Wargrave, have decks, ramps and clad elevations whose joints take movement every day.
