Expansion joint sealing in Thornwood Common, done properly

Few joints take as much punishment as those in a car park. Tyres load the edges, and de-icing salts and water work into any gap, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement and the work can be phased so parts of the car park stay open. If you have damp inside where a wall movement joint has failed and joints where the bead has lost adhesion, we can help, on podiums and floor movement joints, brickwork movement joints and blockwork control joints alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Thornwood Common is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Smaller community and commercial buildings around Thornwood Common have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Thornwood Common: questions and answers

Will you take on work at estates like Woodside Industrial Estate, close to Thornwood Common?

Yes. Estates, retail parks and business parks around Thornwood Common, Woodside Industrial Estate among them, are all within reach. A few photos and the unit address let us price the work.

Do you take on work at healthcare sites like Saint Margaret's Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

How do I request a quote?

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

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Do you offer coloured sealant?

That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Do you reseal car park expansion joints?

Yes. Let us know the opening hours and which levels or bays have to stay available.

Why has the sealant in our expansion joints split?

Normally the joint is moving more than the sealant can take. That’s why we check width, depth and movement class before quoting, rather than replacing like for like.

Site staff or a sealant specialist?

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

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.

On site: what to expect

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Jobs in and around smaller places like Thornwood Common are normally planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We look at the joints, their width and how they’ve failed.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. We strip out the old seal and prepare the faces.
  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. Each joint is inspected and handed over with our 12-month guarantee.

Getting the site ready

  • Flag any permit to work we will need
  • Warn occupants and staff about the work
  • Point out any areas we must not close

Quotes

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

Advice

What happens if it’s left?

A like-for-like reseal of a joint that keeps splitting rarely lasts. If the joint is too narrow or the product wrong for the movement, it needs a different approach, and we’ll say so before quoting. One visit to deal with every failing joint makes more sense than several trips to a place like Thornwood Common. Photos of every joint help us quote for the whole job.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What you get with us

  • Matching to RAL references, product permitting
  • 12-month guarantee on workmanship
  • One contact handling all your sites
  • Colours confirmed for the specified product

What affects the price in Thornwood Common

A fixed quote reflects the actual work. It takes account of:

  • Distance, for remote addresses
  • The size and state of each joint
  • Specialist products, such as fire-rated or hygienic sealants
  • How much there is to seal

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Before you send an enquiry

To price the job accurately, we need to understand the site. Send us:

  • Approximate linear metres or a joint schedule
  • Where the site is, with the postcode
  • Clear photos of the problem areas
  • Specification clauses that apply

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Honest limits

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

  • Concrete or masonry repairs along the arrises
  • Changing the joint layout or spacing of a structure
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

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

Joints and surfaces we work on

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