Expansion joint sealing for commercial buildings in Crowthorne

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load. We’ll tell you if the edges need repairing before sealing, and phased work keeps areas in use. If you’re dealing with expansion joints filled with dirt and stones and water getting into the wall through a failed joint, we can help, on podiums and floor movement joints, precast concrete panel joints and brickwork movement joints alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Crowthorne it comes down to the same thing: the right product in a properly prepared joint.

Towns such as Crowthorne usually have an industrial estate or a few business units, with warehouse floors and loading areas. Smaller units can’t stop work for long, so we plan around the occupier’s hours.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

How the quote is worked out

We price every job individually. The things that drive the figure:

  • Induction, permit and paperwork requirements
  • Whether old sealant has to be cut out first
  • Working within restricted access windows
  • Access and working height

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Sending details for a quote

It doesn’t need to be a full survey. These details are enough to start:

  • Specification clauses that apply
  • Clear photos of the problem areas
  • Any dates the work must fit around
  • Asbestos survey details if the building is older

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Commercial clients in Crowthorne

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

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 we check in with your contact before moving on to each new area. For a town like Crowthorne, we try to group jobs for the same client into one visit. Give us your access times and we’ll fit the work in.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Getting the site ready

  • Arrange parking or a loading space
  • Tell us what induction or permit system the site runs
  • Tell us your opening times and when work is allowed

Getting a fixed quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or send details through our quote form.

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Expansion joint sealing around Crowthorne: what changes locally

Central London is about 32 miles from Crowthorne. Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day. Crowthorne 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.

Hospital campuses such as Broadmoor Hospital, 0.9 miles east of Crowthorne, grow in stages, leaving movement joints wherever new blocks meet old. In a school such as Crowthorne Church of England Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Crowthorne is about 3 miles south-west of Bracknell, in Wokingham. We send applicators to Crowthorne for movement joints, handled exactly as we handle every other area. Crowthorne is one of 42 places in Wokingham on our list. Reading is covered too, some 9 miles away.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Changing the joint layout or spacing of a structure
  • Movement on a scale no sealant is meant to absorb

If you’re not sure, just give us a call on 01277 525 020 or email us and we’ll give you a straight answer before you book.

Signs you need expansion joint sealing in Crowthorne

Weathering wears down sealant on exposed elevations and decks. UV hardens the surface, and the sealant loses its ability to stretch, so it can’t follow the movement any more.

Clients normally get in touch after noticing one or more of the following:

  • Sealant pulling off the joint face
  • Expansion joints split through the centre of the bead
  • Spalled or broken joint edges in floors and decks
  • Rain penetration at brick or block movement joints

For buildings at a park such as Wellington Business Park, 1 mile to the south-west of Crowthorne, brick and panel movement joints are easy to forget until one leaks.

FAQs: Crowthorne

Does your area include sites such as Wellington Business Park, near Crowthorne?

Yes, sites like Wellington Business Park are within our area, along with the rest of Crowthorne. Photos and a short description are enough for a first look.

Does a site in Crowthorne have to shut while its joints are sealed?

Rarely. Work is phased around your operations. The phasing plan comes with the quote.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

How do I request a quote?

You can use the quote form on this site; alternatively, call 01277 525 020 or email us. Include photographs or drawings if you have them.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

What exactly is a movement joint?

The terms overlap a great deal. Both let materials grow and shrink with temperature, moisture and load, and the seal across it keeps water and debris out.
