Expansion joint sealing in Sweethaws, done properly

Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels. We will tell you if the edges need repairing before sealing, and phased work keeps areas in use. The enquiries we see most involve rain penetration at brick or block movement joints and hardened, cracked sealant on exposed facades, across brickwork movement joints, cladding panel joints and precast concrete panel joints. Whoever orders the work in Sweethaws, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

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

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Common questions from Sweethaws clients

Is a hospital such as Crowborough War Memorial Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Is Sweethaws too small for you to travel to?

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

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Can the sealant be colour-matched?

That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

How do you deal with asbestos in old sealant?

The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

What hours do you work?

We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

What if the joint edges are damaged?

A bond is only as strong as the material behind it, so we will tell you if the edges need repairing before sealing. Where it’s visible beforehand, we will say so when we quote.

What sets the cost

What shapes the price:

  • Travel to remote or island sites
  • How much there is to seal
  • The product specified
  • The site’s rules and procedures

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Details that help us quote

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Whether the building will be occupied during the work
  • Any dates the work must fit around
  • Specification clauses that apply
  • Access details, including height

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

Slabs, ramps and loading bays in Sweethaws

Sweethaws sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in. At about 34 miles from central London, Sweethaws is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift.

Sites like Crowborough War Memorial Hospital, 1.3 miles north-east of Sweethaws, carry ambulances, deliveries and visitors’ cars over their road and deck joints. Schools such as Beacon Academy have movement joints in their walls and floors that are easy to overlook.

Sweethaws is about 2 miles south-west of Crowborough, in East Sussex. Sweethaws sits inside our coverage and the rest of East Sussex, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 308 places across East Sussex fall within our area, Sweethaws among them.

Surface by surface

Podium joints

Podiums take foot traffic, planters and weather. We choose a product that copes with feet, wheels and weather.

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement, and confirm it in the quote.

When it isn’t the sealant

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Leaks coming from the membrane rather than the joint seal

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

Surfaces we seal

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

Building owners, agents and FMs in Sweethaws

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Do you need expansion joint sealing in Sweethaws?

Car park decks and floors face loads that walls never see. Wheel loads stress the sealant and the arrises. The product has to be suited to the traffic.

Clients typically get in touch after noticing something like this:

  • Torn sealant in brick or block movement joints
  • Chipped joint edges on forklift routes
  • Expansion joints filled with dirt and stones
  • Sealant pulling off the joint face

Across sites such as Beacon Business Park, 2 miles to the east of Sweethaws, floor and movement joints can be sealed in phases so units keep working.

Comparing quotes

  • Whether primer will be used where the manufacturer specifies it
  • How joint depth will be controlled
  • Whether their applicators hold CSCS cards
  • Their plan for phasing and protecting the area

Questions to ask before you appoint anyone

Diagnose, treat, sign off

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If others near Sweethaws need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. First the joints are inspected, widths measured and the type of failure noted.
  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. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied 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

  • Warn occupants and staff about the work
  • Tell us your opening times and when work is allowed
  • Arrange parking or a loading space
