Expansion joint sealing near Marlow

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

Expansion joint sealing in Marlow

Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Movement joints are where that movement is absorbed. We seal and reseal movement joints in walls, panels, decks and floors on sites in Marlow. If you are dealing with rain penetration at brick or block movement joints and expansion joints split through the centre of the bead, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Marlow it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Car parks and yards in towns like Marlow take tyre loads and, in winter, de-icing salt. Catching a joint before its edges break is the simpler route.

Our workmanship is guaranteed for 12 months, in Marlow as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Surface by surface

Brickwork and blockwork joints

Mortar snots and debris in the joint stop it working. We clear the joint fully before sealing and flag any joint that seems undersized.

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability, and we will confirm the colours available for the specified product.

Your questions answered

Will our site in Marlow 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. We agree the sequence and timings with you before we start.

Does your area include sites such as Globe Business Park, near Marlow?

Yes. We cover Marlow and the area around it, including industrial estates, business parks and retail parks such as Globe Business Park. Photos and a short description are enough for a first look.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

How do I request a quote?

You can use the quote form on this site; alternatively, call 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Which product is best for expansion joints?

It depends on the movement, exposure and traffic. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints unless the specification names something else.

Are you CHAS accredited?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • A joint that has to be widened or re-detailed before it can work
  • Proprietary pre-formed expansion joint systems

If in doubt, speak to us on 01277 525 020 or email drawings and photos and we’ll say what we think.

Joints and surfaces we work on

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

Warehouse floors and decks around Marlow

Marlow is about 30 miles from central London. The roads out of London are lined with trade parks and distribution sheds. At least three named trading, business or retail sites lie within about 3 miles of Marlow. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

A healthcare site such as Marlow Community Hospital, under half a mile east of Marlow, depends on car parks, ramps and service yards whose joints take traffic all day. Schools like Holy Trinity Church of England (Aided) School often have long brick elevations with movement joints that age quietly. A campus such as Buckinghamshire New University (Wycombe Campus), 3.9 miles to the north of Marlow, has long runs of movement joint in its buildings, decks and paving.

Marlow is about 4 miles south of High Wycombe, in Buckinghamshire. Any commercial site in Marlow is covered, whether it’s a single job or part of a planned programme. Our Buckinghamshire coverage takes in 308 places, large and small. Reading is covered too, some 12 miles away.

Leave it or put it right?

Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now, as damage continues meanwhile. We can split the scope into urgent and planned. In Marlow, as anywhere, the simplest time to fix a failed joint is before it leaks. Once water gets in, there’s drying out and making good as well.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

On site: what to expect

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Most work in Marlow is one building at a time: a school, a unit, an office or a block. We start with your photographs, drawings or a site visit, then send a fixed quote.

  1. We start with photographs, 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. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Getting the site ready

  • Let us know about inductions and permits
  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings

Advice

Should maintenance staff do it?

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
