Expansion joint sealing near Fernham

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Why it’s worth doing now in Fernham

Spot repairs can be useful on a tight budget. But if the rest of the run is the same age and product, it’s usually not far behind. We can price a patch and a full reseal side by side. One visit to deal with every failing joint makes more sense than several trips to a place like Fernham. Photos of every joint help us quote for the whole job.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

What you get with us

  • Colours confirmed for the specified product
  • Health and safety: CHAS accredited
  • Coloured sealants to suit the setting, where available
  • Clear, fixed quotes

Expansion joint sealing in Fernham, done properly

Few joints take as much punishment as those in a car park. Tyres load the edges, and de-icing salts and water work into any gap, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement and the work can be phased so parts of the car park stay open. Most enquiries involve movement joints with split or torn sealant and joints packed with grit and debris, on brickwork movement joints, precast concrete 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: in Fernham, that means joint design, primers and backing rod as standard.

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

We stand by our work with a 12-month guarantee. That covers our preparation and application.

Site staff or a sealant specialist?

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Questions we’re asked in Fernham

Can you work at a site such as Faringdon Business Park, by Fernham?

Yes. Our area takes in Fernham and its surroundings, with estates and business parks such as Faringdon Business Park included. To start, just speak to us on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Is Fernham too small for you to travel to?

No. Small places get the same service as large ones. 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.

Can you send site paperwork?

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 you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it.

How long does movement joint sealing take?

That depends on joint lengths, widths, access and how much old sealant or filler needs removing. As a guide, it usually takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

After the work

After handover, a little attention goes a long way:

  • Inspect exposed joints once the cold weather has passed
  • Brief car park operatives to protect joint lines during winter clearance
  • Treat a small split as a warning, not a cosmetic issue
  • Leave barriers in place until fresh joint sealant has cured

Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.

Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint. Resealing promptly prevents internal damage.

Traffic, movement and joints around Fernham

Fernham sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint. At least three named trading, business or retail sites lie within about 3 miles of Fernham. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

For a school such as Faringdon Community College, playground and building joints can be done in the holidays. Hospital campuses such as Faringdon Day Hospital, 2.2 miles north of Fernham, grow in stages, leaving movement joints wherever new blocks meet old. Phasing is what makes joint work possible on busy sites such as Stanford in the Vale Business Park (2.6 miles east of Fernham): one bay, aisle or car park row at a time.

Cost factors for movement joints

A fixed quote reflects the actual work. It takes account of:

  • Specialist products, such as fire-rated or hygienic sealants
  • Site requirements such as inductions and permits
  • The size and state of each joint
  • Any access equipment needed

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

What to include in your enquiry

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

  • The type of building and who uses it
  • The postcode of the building
  • Asbestos survey details if the building is older
  • Photos of the joints, close up and from further back

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or send details through our quote form with what you know.

What sealant work can’t fix

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Changing the joint layout or spacing of a structure
  • Movement on a scale no sealant is meant to absorb
  • Damaged metal nosings or cover plates over a joint

If in doubt, ring 01277 525 020 or use the quote form and we’ll say what we think before you book.

Joints and surfaces we work on

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

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. If others near Fernham need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Have the specification and drawings to hand
  • Explain the parking and delivery arrangements

Quotes

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
