Expansion joint sealing in Bagshot

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

Expansion joint sealing in Bagshot

The seal is what lets a movement joint do its job. When the sealant splits or lets go, the gap fills with dirt and water, the joint can’t close properly and its edges begin to crumble. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. If you’re dealing with brittle, chalky sealant on external joints and torn sealant in brick or block movement joints, we can help. One point of contact handles commercial sealant work in Bagshot from the first photographs to the final walk-round, whether it’s one building or several.

Around smaller places such as Bagshot, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

FAQs: Bagshot

Does your area include sites such as Stype Business Centre, near Bagshot?

Yes. We cover Bagshot and the area around it, including industrial estates, business parks and retail parks such as Stype Business Centre. Send details of the unit and the work through our quote form for a quick quote.

Do we have to stop operations in Bagshot while the joints are sealed?

Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we will plan from there.

Does the weather affect joint sealing?

A wet joint can’t be sealed properly. We agree a revised date with you.

Will you come and look before quoting?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.

When is resealing likely to be due?

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.

Why do our movement joints keep failing?

Most often the movement is too much for the product or the joint width. We review the joint design as well as the sealant before pricing.

Do you guarantee expansion joint work?

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

From enquiry to sign-off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next. Rural sites near Bagshot may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  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. 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. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  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.

Before we start on site

  • Flag any permit to work we will need
  • Have the specification and drawings to hand
  • Tell us your opening times and when work is allowed

Commercial clients in Bagshot

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.

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.

How the quote is worked out

What shapes the price:

  • Access and working height
  • How much there is to seal
  • Travel to remote or island sites
  • Whether old sealant has to be cut out first

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What we need to price the job

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Approximate linear metres or a joint schedule
  • The site address and postcode
  • Specification clauses that apply
  • The asbestos register, for older buildings

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Looking after the joints

Once the work is signed off, a little attention goes a long way:

  • Brief car park operatives to protect joint lines during winter clearance
  • Inspect movement joints alongside other routine building checks
  • Avoid parking heavy plant or pallets on joint lines
  • Treat a small split as a warning, not a cosmetic issue

Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file, so the next reseal starts with the facts.

When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort. We can suggest an order, worst joints first.

When it isn’t the sealant

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

  • 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 call 01277 525 020 or email the details over and we’ll tell you honestly.

What we seal

  • Cladding panel joints
  • Podiums and floor movement joints
  • Blockwork control joints
  • Car park decks and ramps
  • Precast concrete panel joints
  • Brickwork movement joints

Common problems we fix in Bagshot

Some joints were never sealed with the right product. Products not classed for the movement fail early. Movement capability is set out in BS EN ISO 11600, and specifications often refer to it.

Any of the following is a good reason to get the joints checked over:

  • Car park joints leaking onto vehicles below
  • New sealant over old, now failing
  • Rain penetration at brick or block movement joints
  • Spalled or broken joint edges in floors and decks

Another example is Hungerford Trading Estate, 2 miles to the north-east of Bagshot, where floors and yards would be done in stages around the occupiers.

Questions to ask before you book

  • Is the sealant right for the movement and the substrate?
  • How long is the guarantee, and what does it include?
  • Are they CHAS accredited or on Constructionline?
  • Their plan for phasing and protecting the area

Where floor joints take the most wear near Bagshot

The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints. Bagshot has at least three named business or industrial parks inside a 3-mile radius. Their warehouses, yards and car parks are exactly where joints take the most punishment.

Business parks such as Stype Business Centre (to the south-east of Bagshot) have car parks, paved areas and long brick and panel elevations, all with movement joints. Schools like John O'Gaunt School often have long brick elevations with movement joints that age quietly.
