Expansion joint sealing near Horncastle

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

General trades versus a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Expansion joint sealing in Horncastle

Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking and the seal across each one keeps out water and grit. We seal and reseal movement joints in walls, panels, decks and floors. If you’re dealing with torn sealant in brick or block movement joints and sealant pulling off the joint face, we can put it right, whatever the surface. Whoever orders the work in Horncastle, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Small units near places like Horncastle are often converted farm buildings with new concrete floors. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Leave it or put it right?

Resealing is typically the answer, not replacing the element. Where the edges are sound, cutting out and resealing is enough. We’ll flag where edges need repair before sealing. For buildings in places like Horncastle, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

What affects the price in Horncastle

Each job is priced on its own details. The things that drive the figure:

  • Location, for remote and island sites
  • Backing rod, priming and other preparation
  • Quantities, in metres or numbers
  • Whether the work must be split into stages

The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

Sending details for a quote

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

  • How the joints are reached, and at what height
  • Drawings or a marked-up plan, if available
  • Specification clauses that apply
  • Any dates the work must fit around

To get a fixed quote, ring 01277 525 020 or send details through our quote form. Our quote form is another easy route.

Traffic, movement and joints around Horncastle

Horncastle is about 40 miles from central London. Warehousing clusters around the motorways that ring and radiate from London. The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in.

Business parks such as British Estates Business Park (to the east of Horncastle) have car parks, paved areas and long brick and panel elevations, all with movement joints. Another example is Meadway Shopping Centre, under half a mile north-east of Horncastle, where floors and yards would be done in stages around the occupiers. For estates staff at a university like University of Reading (2.8 miles east of Horncastle), building and paving joints are part of the planned maintenance list.

Horncastle is about 2 miles west of Reading, in Reading. Horncastle sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Reading coverage takes in 17 places.

If you need expansion joint sealing in RG30 and RG31, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Streets here include Low Lane, Usk Road and Mill Lane, and sites on any of them can send details for a fixed quote. Close to Horncastle, our area also takes in Fords Farm (1 mile south), Southcote (1 mile east), Tilehurst Within (1 mile north), Beansheaf Farm (1 mile south-west) and Burghfield Bridge (1 mile south).

Honest limits

We check first that sealant really is the fix. It won’t put right:

  • Damaged metal nosings or cover plates over a joint
  • Leaks coming from the membrane rather than the joint seal
  • A joint that has to be widened or re-detailed before it can work

Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we will tell you honestly.

From enquiry to sign-off

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. What matters most for a job in Horncastle is a clear list of what needs doing. You’ll then get a fixed price for the work.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
  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. We check every joint before sign-off, and the work carries our 12-month guarantee.

Before we start on site

  • Tell us which areas need to stay in use
  • Tell staff and tenants when we’ll be in

Common questions from Horncastle clients

Is a hospital such as Prospect Park Hospital somewhere you can work?

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.

Does your area include sites such as British Estates Business Park, near Horncastle?

Yes. Estates, retail parks and business parks around Horncastle, British Estates Business Park among them, are all within reach. A few photos and the unit address let us price the work.

Do you use silicone or polyurethane in movement joints?

The right product depends on the joint. Facades often take a low-modulus silicone; floors and decks usually need a polyurethane unless the specification names something else.

What will the job cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Is movement joint sealing guaranteed?

Each job is backed by a 12-month guarantee on the workmanship. The guarantee covers how we sealed, not damage caused afterwards.
