About our expansion joint sealing in Runfold

Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises and the bead bonds to the sides, never the back. If you have spalled or broken joint edges in floors and decks and rain penetration at brick or block movement joints, we can help, on podiums and floor movement joints, cladding panel joints and blockwork control joints alike. A specialist sealant contractor works differently from a general builder: on jobs in Runfold, preparation and product choice get the time they need.

Around smaller places such as Runfold, 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.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Runfold: questions and answers

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

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Will you take on work at estates like The Sands Business Centre, close to Runfold?

Yes. Our area takes in Runfold and its surroundings, with estates and business parks such as The Sands Business Centre included. Photos and a short description are enough for a first look.

Can you work on car park ramps and decks?

Yes. Tell us how the car park is used and which areas must stay open, and we will plan the phasing around it.

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.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

What sealant do you use in movement joints?

Whatever suits the joint and the specification. The quote states the sealant and its movement class so there are no surprises.

Commercial clients in Runfold

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Keeping the joints sound

For the best life from the joints:

  • Check joints after long freezing spells
  • Keep traffic off new joints until the cure time is up
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Brief car park operatives to protect joint lines during winter clearance

Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. Regular sweeping keeps joint lines clear.

A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Sealing the joint promptly stops it at source.

From enquiry to sign-off

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. If others near Runfold need work, visits can be combined. A fixed quote is given before anything starts.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  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. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Getting the site ready

  • Tell us your opening times and when work is allowed
  • Clear stock, furniture or equipment away from the joints
  • Arrange parking or a loading space

Warehouse floors and decks around Runfold

Less than 3 miles from Runfold there are at least three named estates and business parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Runfold is in the South East, one of the UK’s drier regions. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints.

For buildings at a park such as The Sands Business Centre, less than half a mile north-east of Runfold, brick and panel movement joints are easy to forget until one leaks. Sites like Farnham Community Hospital (1.5 miles north-west of Runfold) carry ambulances, deliveries and visitors’ cars over their road and deck joints. At a retail site such as Farnham Retail Park, 1.4 miles to the west of Runfold, trolleys, cages and cars run over floor and slab joints all day.

Why it’s worth doing now in Runfold

Combining joint work with other maintenance reduces set-up costs. Leaking joints need sealing now. Urgent joints now, the rest later, is often the sensible plan. One visit to deal with every failing joint makes more sense than several trips to a place like Runfold, rather than one at a time. Send photos of each area and we will quote for the lot.

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

Why appoint us

  • Failed material removed, not covered up
  • A range of standard colours, depending on the product
  • Commercial sealant work since 2005
  • Constructionline member

General trades versus a specialist

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

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What affects the price in Runfold

Before we quote, we look at:

  • Specialist products, such as fire-rated or hygienic sealants
  • Induction, permit and paperwork requirements
  • Travel to remote or island sites
  • How accessible the joints are

A quote for movement joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Before you send an enquiry

Good information means a firmer quote. When you get in touch, include:

  • The site address and postcode
  • Approximate linear metres or a joint schedule
  • Any specification or named product
  • A wide shot and a close-up of the area

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
