Questions about Farnham

Is a hospital such as Herts And Essex Community Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you work at a site such as Birchanger Industrial Estate, by Farnham?

Yes. Estates, retail parks and business parks around Farnham, Birchanger Industrial Estate among them, are all within reach. A few photos and the unit address let us price the work.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure.

Do you need to see the site first?

It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs typically get a visit.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

Expansion joint sealing in Farnham

If you need expansion joint sealing in Farnham, start with photographs and joint lengths. Send them through our quote form, and we will arrange a site visit if needed. To discuss the joints first, ring 01277 525 020 or use the quote form. Most enquiries involve previous reseals laid over old sealant and expansion joints filled with dirt and stones, across brickwork movement joints, precast concrete panel joints and podiums and floor movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Farnham, preparation and product choice get the time they need.

Jobs around smaller places like Farnham 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.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When something else is needed

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Cracking or settlement that calls for an engineer’s assessment
  • Changing the joint layout or spacing of a structure

If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think before you book.

Surfaces we seal

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

Signs you need expansion joint sealing in Farnham

The edges of the material can fail rather than the sealant. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip.

Things that normally lead to an enquiry:

  • Sealant peeling off one face of the joint
  • Rain penetration at brick or block movement joints
  • Torn sealant in brick or block movement joints
  • Arrises breaking up along floor joints

Schools like Farnham Church of England Primary School often have long brick elevations with movement joints that age quietly.

Before you book anyone

  • Can the work be phased to keep areas open?
  • How the existing material will be dealt with
  • Health and safety accreditation such as CHAS
  • Whether primer will be used where the manufacturer specifies it

How to choose a sealant contractor

When to bring in a specialist

Certain joints really need a specialist: 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 prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Cost factors for movement joints

The price varies from site to site. It mainly depends on:

  • Travel to remote or island sites
  • Working within restricted access windows
  • Joint width, depth and condition
  • How much there is to seal

Pricing movement joints depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

Before you send an enquiry

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • Any specification or named product
  • Anything awkward about access or site hours
  • Photos of the joints, close up and from further back
  • Drawings or a marked-up plan, if available

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings you can plan around. If you have questions first, speak to us on 01277 525 020 or email us.

Warehouse floors and decks around Farnham

Farnham 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, while winter salting gets into any joint left open. At least three named trading, business or retail sites lie within about 3 miles of Farnham. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Sites like Herts And Essex Community Hospital (to the south-east of Farnham) carry ambulances, deliveries and visitors’ cars over their road and deck joints. Another example is Stort Valley Industrial Estate, 1.8 miles south-east of Farnham, where floors and yards would be done in stages around the occupiers.

What the job involves on each surface

Internal floor movement joints

Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.

Concrete and precast panel joints

Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond, so the new seal holds.

Diagnose, treat, sign off

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. For a building around Farnham, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Finished joints are checked and backed by our 12-month guarantee.

What we need from you

  • Point out any areas we must not close
  • Confirm the product named in the specification
  • Arrange parking or a loading space
