Expansion joint sealing across Enfield

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

How we handle expansion joint sealing in Enfield

Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied with primer where the maker calls for it. If you have brittle, chalky sealant on external joints and layers of sealant in a movement joint, we can help, whatever the surface. A single leaking joint is often how a building in Enfield first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Areas such as a loading bay or car park deck in Enfield typically have to stay in use. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.

A 12-month guarantee applies to all our work. If an installation problem shows up, ring 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

Questions about Enfield

Do you take on work at healthcare sites like St Michael's Community Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Can you work in a London building with booked loading and goods-lift slots?

Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry.

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.

Can you quote from photographs?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

What do you charge?

That depends on the job: quantities, access, the product and any phasing. Call for a quote.

Which product is best for expansion joints?

It depends on the movement, exposure and traffic. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints, and the specification has the final say.

Do the joint edges need to be sound before sealing?

Sealant needs sound faces to bond to, so broken or crumbling edges have to be repaired first. We flag it at the quote stage where we can see it.

Commercial clients in Enfield

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

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

How a job runs

We schedule the visit to fit the site hours and access windows you give us. 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 job in Enfield, access comes first. Give us the hours we can be on site and we’ll schedule to suit.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Before we start on site

  • Point out any areas we must not close
  • Tell staff and tenants when we will be in
  • Have the specification and drawings to hand

What affects the price in Enfield

There’s no standard rate for sealant work, because every site is different. What we look at:

  • How much there is to seal
  • Whether old sealant has to be cut out first
  • Which sealant the job calls for
  • The size and state of each joint

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

Before you send an enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • A wide shot and a close-up of the area
  • Specification clauses that apply
  • The site address and postcode
  • Your programme or deadline

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or email us with what you know.

Surface by surface

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement.

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it, so the new seal holds.

Expansion joint sealing around Enfield: what changes locally

Few London car parks or loading bays can be taken out of use for more than a short spell, so we seal in sections and hand areas back as each cures. The 3 miles around Enfield take in at least three named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

Enfield is inside London’s ULEZ, as is the rest of Greater London; tell us about loading bays, goods lifts and parking when you send details. In a school such as Enfield Grammar School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Retail parks like Colosseum Retail Park (to the east of Enfield) have long runs of car park and yard joints taking daily traffic.

Enfield is about 9 miles north of St Pancras, in Greater London. We send applicators to Enfield for movement joints, handled exactly as we handle every other area. We work across 764 places in Greater London. Sites around London have their own page, roughly 11 miles from Enfield.

Anyone looking for expansion joint sealing in EN1, EN2 and N21 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. We cover commercial and managed buildings on Lea Road, Farr Road and Cecil Road. Access to Enfield is via the A110 among other routes, so getting applicators and materials to site is simple. Just outside Enfield, we also work in Bush Hill Park (1 mile south-east), Bush Hill (1 mile south), Enfield Chase (1 mile west), Gordon Hill (1 mile north) and Forty Hill (1 mile north-east). Nearby towns on our patch include London (11 miles south), City of Westminster (10 miles south), Marylebone (10 miles south), Kensington (12 miles south-west), St Pancras (9 miles south) and Shoreditch (9 miles south).

Around Enfield

Around Enfield, our work takes us to commercial buildings near Kings Head pub, St Andrew's CofE Primary School and Enfield Town Park and the streets around them. Enfield has its own railway station: Enfield Town station. Other landmarks nearby include Museum of Enfield (under half a mile south) and St Michaels Hospital (0.7 miles north). For a walk, there’s Bowyer's Water and Pole Hill.

When to bring in a specialist

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What we can’t put right

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Movement on a scale no sealant is meant to absorb
  • A joint that has to be widened or re-detailed before it can work
  • Broken or spalled joint edges, which need repairing before any sealant goes in

If you are not sure, just ring 01277 525 020 or send details through our quote form and we’ll give you a straight answer.
