Expansion joint sealing across Dedham Heath

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Our process

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and we clear our waste as we work. Jobs in and around smaller places like Dedham Heath are typically planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Preparing the site

  • Agree which areas must stay open
  • Point out parking and an unloading spot
  • Send your site hours and access windows

About our expansion joint sealing in Dedham Heath

If you need expansion joint sealing in Dedham Heath, start with photographs and joint lengths. We’ll come and look where photos don’t show enough. You can also call 01277 525 020 or email a schedule or drawings to talk the joints through. We work on brickwork movement joints, cladding panel joints and blockwork control joints, and the failures we are asked to look at most are weathered movement joint sealant that no longer flexes and rain penetration at brick or block movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Dedham Heath is the same: the right product in a properly prepared joint.

Around smaller places such as Dedham Heath, 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.

A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or email us and we will come back to it.

Leave it or put it right?

Re-sealing with the same product that failed is often a false economy. 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. Around Dedham Heath, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we’ll quote for the lot.

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Different surfaces, different methods

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.

Podium joints

Podium decks are exposed and often trafficked. We choose a product that copes with feet, wheels and weather.

Slabs, ramps and loading bays in Dedham Heath

Dedham Heath lies roughly 56 miles out from central London. 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. Dedham Heath is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints.

Sites like Severalls Hospital, 4.7 miles west of Dedham Heath, carry ambulances, deliveries and visitors’ cars over their road and deck joints. Phasing is what makes joint work possible on busy sites such as Blue Barns Business Park (2.1 miles west of Dedham Heath): one bay, aisle or car park row at a time.

Common problems we fix in Dedham Heath

Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again unless width and product are reviewed.

Things that normally lead to an enquiry:

  • Car park joints leaking onto vehicles below
  • Water getting into the wall through a failed joint
  • Torn sealant in brick or block movement joints
  • Layers of sealant in a movement joint

Schools such as Dedham Church of England Voluntary Controlled Primary School have movement joints in their walls and floors that are easy to overlook.

What to look for in a quote

  • What the guarantee covers, and for how long
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How they’ll work around occupants
  • The named product and why it was chosen

How to choose a sealant contractor

After the work

Regular inspection catches problems early. In particular:

  • Keep racking legs and heavy point loads off floor joints
  • Check joints after long freezing spells
  • Note which joints were done, when, and with what
  • Report split or peeling joint sealant early

Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records.

Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors. Catching it early keeps the water outside.

What sets the cost

Each job is priced on its own details. The main factors are:

  • Whether the work must be split into stages
  • How accessible the joints are
  • Backing rod, priming and other preparation
  • The total length or number of joints

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

What we need to price the job

A good diagnosis starts with the right details. Tell us:

  • The asbestos register, for older buildings
  • Any specification or named product
  • Rough lengths or quantities, or drawings if you have them
  • When you need the work done

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or send photos by email.

Questions we’re asked in Dedham Heath

Is hospital work, at somewhere like Severalls Hospital, something you do?

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

Is Dedham Heath too small for you to travel to?

No. Places such as Dedham Heath are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Is any job too small?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Which product is best for expansion joints?

The specification comes first, then the joint’s movement and exposure. We name the proposed product in the quote so there are no surprises.

How long before the joints can be used?

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

What hours do you work?

Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
