About our expansion joint sealing in Roxwell

The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in, 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. We work on precast concrete panel joints, blockwork control joints and cladding panel joints, and what we are called in for most is sealant peeling off one face of the joint and movement joints with split or torn sealant. A single leaking joint is often how a building in Roxwell 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.

Halls, schools and small commercial buildings near places like Roxwell have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What affects the price in Roxwell

We price every job individually. The main factors are:

  • Whether old sealant has to be cut out first
  • The site’s rules and procedures
  • Backing rod, priming and other preparation
  • Specialist products, such as fire-rated or hygienic sealants

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What we need to price the job

For an accurate fixed quote, we need to understand the site. Send us:

  • Any dates the work must fit around
  • The asbestos register, for older buildings
  • A wide shot and a close-up of the area
  • Specification clauses that apply

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Diagnose, treat, sign off

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a building around Roxwell, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  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. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Before we start on site

  • Tell staff and tenants when we’ll be in
  • For older buildings, check the asbestos register before work
  • Tell us which areas need to stay in use

What we are called out for in Roxwell

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears.

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

  • Sealant pulling off the joint face
  • Layers of sealant in a movement joint
  • Arrises breaking up along floor joints
  • Weathered movement joint sealant that no longer flexes

Campuses like Writtle University College Cow Watering Campus (to the south-east of Roxwell) mix old and new buildings, with movement joints wherever they meet.

Questions to ask before you book

  • What the guarantee covers, and for how long
  • The named product and why it was chosen
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • What site paperwork they can supply

Choosing a commercial sealant contractor

Expansion joint sealing around Roxwell: points for this area

The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints. At about 27 miles from central London, Roxwell is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds, and their floor joints take forklift and pallet-truck traffic all day.

Hospitals like Chelmsford and Essex Hospital, 3.9 miles south-east of Roxwell, have multi-storey or surface car parks whose joints carry vehicles round the clock.

Roxwell is about 4 miles west of Chelmsford, in Essex. Any commercial site in Roxwell is covered, whether it’s a single job or part of a planned programme. 644 places across Essex fall within our area, Roxwell among them. There’s a separate page for London, roughly 27 miles from Roxwell.

Questions about Roxwell

Will our site in Roxwell have to close for joint sealing?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we will plan from there.

Is Roxwell too small for you to travel to?

Not at all. Roxwell is within our area. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Does the weather affect joint sealing?

The joint has to be dry, and the air and surface temperature inside the product’s limits. Cold, damp or frosty mornings can stop work outside, so we plan with the forecast in mind.

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.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

Do you offer coloured sealant?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

When something else is needed

Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Concrete or masonry repairs along the arrises
  • Leaks coming from the membrane rather than the joint seal

If you are not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Surfaces we seal

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

Leave it or put it right?

Combining joint work with other maintenance reduces set-up costs. Leaking joints need sealing now. Urgent joints now, the rest later, is often the sensible plan. Halls, stores and units around places like Roxwell may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

There’s no price list, since every building and every scope is different. Call for a quote.

What you get with us

  • Colour options checked against the specified product
  • Old sealant cut out, never sealed over
  • One number for every site we cover
  • Work carried out by CSCS-carded applicators

Take a look at how commercial sealant jobs are priced and our accreditations and insurance.

Surface by surface

Concrete and precast panel joints

Joints between precast panels open and close with temperature and loading. We use a sealant classed for the movement, laid over backing to depth.

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler and a flexible sealant where the joint moves more.
