Expansion joint sealing for Magham Down sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Expansion joint sealing for commercial buildings in Magham Down

Brickwork and blockwork walls have vertical movement joints at intervals, and they’re easy to miss until the sealant fails. Failed sealant here lets rain into the wall and can leave the joint full of debris. 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. Most enquiries involve rain penetration at brick or block movement joints and debris jammed in movement joints, on car park decks and ramps, cladding panel joints and blockwork control joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Magham Down, preparation and product choice get the time they need.

Jobs around smaller places like Magham Down are planned so the whole job is done in one visit, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

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.

FAQs: Magham Down

Can you take on a job at a hospital such as Amberstone Hospital?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can you work at a site such as Station Road Industrial Estate, by Magham Down?

Yes. Estates, retail parks and business parks around Magham Down, Station Road Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

Is Magham Down in your area?

Yes. Magham Down is in our area. For a quote, speak to us on 01277 525 020 or send photos by email.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

How long will the joint resealing take?

That depends on joint lengths, widths, access and how much old sealant or filler needs removing. Typically it takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases.

Expansion joint sealing in Magham Down: the local picture

Magham Down sits in one of the drier corners of the country, the South East. 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 46 miles from central London, Magham Down is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day.

Centres like Hailsham Retail Park, 2.3 miles south-west of Magham Down, have mall floors and service decks whose joints carry steady traffic. Across sites such as Crown Close Industrial Estate, 2.2 miles to the south-west of Magham Down, floor and movement joints can be sealed in phases so units keep working. If you manage units on an estate such as Station Road Industrial Estate, 2.1 miles to the south-west of Magham Down, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.

Magham Down is about 2 miles north-east of Hailsham, in East Sussex. Our applicators travel to Magham Down for work on movement joints, handled exactly as we handle every other area. Our East Sussex coverage takes in 308 places. Sites around Brighton have their own page, about 18 miles away.

When to bring in a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

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, which is what makes a joint last.

How the job changes by surface

Concrete and precast panel joints

Joints between precast panels open and close with temperature and loading. The sealant needs the right movement capability and a controlled depth.

Car park decks and ramps

Car park joints are some of the hardest-working joints in any building. We use a sealant made for wheel loads and the expected movement with bays done in phases so the car park keeps running.

Diagnose, treat, sign off

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. For work around Magham Down, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  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

  • Point out parking and an unloading spot
  • Let us know about inductions and permits
  • Tell us which areas need to stay in use

What sets the cost

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • The product specified
  • How much there is to seal
  • Backing rod, priming and other preparation
  • Location, for remote and island sites

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

What we need to price the job

Good information means a firmer quote. Helpful details to send:

  • The product your specification calls for
  • Your programme or deadline
  • A wide shot and a close-up of the area
  • Rough lengths or quantities, or drawings if you have them

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to call 01277 525 020 or send photos by email.

After the work

Regular inspection catches problems early. In particular:

  • Keep product details with the building records for the next reseal
  • Act on the first tear or lifting edge rather than waiting
  • Leave barriers in place until fresh joint sealant has cured
  • Clear dirt from joint lines during routine cleaning

Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal, and it’s worth checking joints once the cold weather has passed.

External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint. Catching it early keeps the water outside.

What we can’t put right

We check first that sealant really is the fix. It isn’t the answer for:

  • Movement on a scale no sealant is meant to absorb
  • A joint that has to be widened or re-detailed before it can work
  • Damaged metal nosings or cover plates over a joint

If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we’ll say what we think.
