Expansion joint sealing for businesses in Lyne

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

Keeping the joints sound

To get the most from the new sealant:

  • Check joints after long freezing spells
  • Report split or peeling joint sealant early
  • Note which joints were done, when, and with what
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints

Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in and long before edges start to break. Should you spot a problem, you can phone 01277 525 020 or send photos by email and send a picture.

Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one, so the work can be planned rather than rushed. We can suggest an order, worst joints first.

Expansion joint sealing for commercial buildings in Lyne

We’ve been sealing expansion and movement joints for over 20 years for contractors, facilities managers and owners. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. We work on cladding panel joints, podiums and floor movement joints and brickwork movement joints, and the usual reasons a site gets in touch are previous reseals laid over old sealant and brittle, chalky sealant on external joints. For commercial sealant work in Lyne, you deal with one contact from quote to sign-off, whether it’s one building or several.

Around smaller places such as Lyne, 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 sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

How a job runs

Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Smaller jobs around Lyne can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Finished joints are checked and backed by our 12-month guarantee.

FAQs: Lyne

Is Hersham Farm Business Park, near Lyne, within your area?

Yes, sites like Hersham Farm Business Park are within our area, along with the rest of Lyne. A few photos and the unit address let us price the work.

Can you take on a job at a hospital such as St Peter's Hospital?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Do you use silicone or polyurethane in movement joints?

Whatever suits the joint and the specification. We name the proposed product in the quote, so you know what’s going in.

What timescale should we allow for resealing expansion joints?

The metres of joint, the access and the amount of removal decide it. As a guide, it normally takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

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

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Expansion joint sealing in Lyne: the local picture

Lyne is about 21 miles from central London. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift. Lyne sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.

Phasing is what makes joint work possible on busy sites such as Hanworth Lane Business Park (1.3 miles east of Lyne): one bay, aisle or car park row at a time. A campus such as Royal Holloway University, 2.9 miles north-west of Lyne, has long runs of movement joint in its buildings, decks and paving. On a site such as Hersham Farm Business Park, 1.1 miles west of Lyne, the movement joints are in car park slabs, paving and building elevations.

Lyne is about 3 miles south of Egham, in Surrey. We cover commercial sites throughout Lyne, for single jobs and planned programmes alike. Across Surrey, 379 places are covered, Lyne among them. Sites around Reading have their own page, roughly 19 miles from Lyne.

We also cover Chertsey (1 mile east), Trumps Green (2 miles west), Ottershaw (2 miles south), Stonehill (2 miles south-west) and Row Town (2 miles south-east). A short drive away, we cover Guildford (10 miles south), Woking (5 miles south), Camberley (9 miles south-west), Epsom (12 miles east), Ewell (12 miles east) and Egham (3 miles north).

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Lyne can sit alongside others in a wider programme.

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. 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.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Movement on a scale no sealant is meant to absorb
  • Damaged metal nosings or cover plates over a joint
  • A joint that has to be widened or re-detailed before it can work

If in doubt, call 01277 525 020 or email the details over and we will say what we think.

Different surfaces, different methods

Internal floor movement joints

Floor joints include saw-cut joints and construction joints. A semi-rigid filler is common in trafficked industrial floors.

Joints between different materials

Different materials meeting at a joint rarely move in step. The product must bond to both substrates and cope with the movement priming where the maker calls for it.
