Floor joint sealing near Hersham

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

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Expect fillers on young slabs to need a top-up
  • Keep trucks off new joints until we say they’re ready
  • Check joint lines on busy aisles regularly
  • Sweep debris out of open joints until they can be filled

Young concrete carries on shrinking, so some fillers part slightly from one face. It is a known trait of new floors and a later top-up deals with it in most cases.

A broken joint on a main route is crossed by every truck on that route. Early treatment protects wheels, loads and drivers as much as the floor.

Floor joint sealing in Hersham

Before quoting, we look at what the floor is telling us: how wide the joints are, signs of ongoing movement, the wheel types crossing them and the state of the arrises. From that we choose between a semi-rigid filler and a more flexible sealant, area by area where it needs to be. We work on forklift and pallet-truck routes, construction joints and saw-cut induced joints, and the usual reasons a site gets in touch are open saw cuts full of debris and filler that has parted from one face. Looking for mastic applicators who cover Hersham? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Around Hersham, most floor and movement joint jobs are single buildings or yards. That way the right materials come on the day and the job is done in one visit where possible.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Hersham: questions and answers

Do you cover business parks and estates near Hersham, such as Hersham Place Technology Park?

Yes. Our area takes in Hersham and its surroundings, with estates and business parks such as Hersham Place Technology Park included. Send details of the unit and the work through our quote form for a quick quote.

Would you work within a site like Walton Community Hospital?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

What site paperwork can you supply?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

How long before trucks can use the joints?

Each product has its own cure time, and cold floors slow it down. We plan the phasing so that waiting time fits your operation.

Is Hersham in your area?

Yes. We cover Hersham and the rest of Surrey, within our coverage of Greater London, South East England and Scotland. To discuss a job, call 01277 525 020 or email the details over.

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.

Common problems we fix in Hersham

Unfilled joints soon pack with grit, shrink-wrap scraps and pallet splinters. That debris is hard and levers at the edges as wheels pass so the arrises break sooner.

These are often picked up first by site or facilities staff:

  • Drivers complaining about joints on a route
  • Soft sealant dragged out of trafficked joints
  • Loading bay joints breaking down
  • A gap opening alongside old joint filler

Schools such as Bell Farm Primary School have movement joints in their walls and floors that are easy to overlook.

How to choose a sealant contractor

What affects the price in Hersham

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • How accessible the joints are
  • Travel to remote or island sites
  • How much there is to seal
  • Which sealant the job calls for

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Details that help us quote

The more we know, the firmer the quote. Helpful details to send:

  • Whether the building will be occupied during the work
  • The postcode of the building
  • Approximate linear metres or a joint schedule
  • Anything awkward about access or site hours

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Work for main contractors and building owners

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.

Joints that move: notes for Hersham

Hersham lies roughly 16 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London. The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open.

University campuses such as Kingston University Penrhyn Road Campus (to the north-east of Hersham) have car parks, paved walkways and building elevations with movement joints. Large sites such as Walton Community Hospital (to the north of Hersham) have car parks, service roads and long elevations with movement joints in brick and panels.

Hersham is about 1 mile south of Walton-on-Thames, in Surrey. We cover Hersham and the rest of Surrey, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 379 places in Surrey, large and small. Our London page has more on work in that area (16 miles or so).

Should maintenance staff do it?

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

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.
