Floor joint sealing across Farnham

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

Leave it or put it right?

Holding off until the whole floor can close can take a long time. Zone by zone, the worst aisles can be dealt with now and the remainder follows on a plan that suits you. One visit to deal with every failing joint makes more sense than several trips to a place like Farnham, rather than one at a time. Send photos of each area and we’ll quote for the lot.

A quote for floor joints depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.

About our floor joint sealing in Farnham

Across Farnham and the rest of Essex, it runs the same way: you send details, we send a fixed quote, the joints are done and the 12-month guarantee follows. A rough length of joint, photos of the worst areas and a site plan let us give a quick quote and a visit can be arranged where that is easier. Site teams most often ask us about scruffy, dirty joint lines on a shop or showroom floor and dock area joints that have failed first, across retail and showroom floors, forklift and pallet-truck routes and saw-cut induced joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Farnham it comes down to the same thing: the right product in a properly prepared joint.

In and around smaller places like Farnham, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Floors, slabs and movement joints in Farnham

Less than 3 miles from Farnham 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. At about 30 miles from central London, Farnham is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds.

A healthcare site such as Herts And Essex Community Hospital, 2.8 miles south-east of Farnham, depends on car parks, ramps and service yards whose joints take traffic all day. Schools like Farnham Church of England Primary School often have long brick elevations with movement joints that age quietly. Another example is Stort Valley Industrial Estate, which lies south-east of Farnham, where floors and yards would be done in stages around the occupiers.

How the job changes by surface

Isolation joints at walls and columns

We plan column and wall joints around racking and fixed plant so nothing has to move unexpectedly.

Saw-cut induced joints

Sawn joints make up most of the joint length in a typical industrial floor. We clear them back to clean concrete and fill them to the depth the product calls for, finishing flush with the slab.

Site staff or a sealant 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. Getting these wrong typically costs more in the end than doing them right.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Farnham may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. First, the zones and order of work are agreed with you.
  2. We point out joints whose edges need repairing first.
  3. We clear each run back to clean concrete.
  4. The chosen filler or sealant goes in flush with the slab.
  5. You get a time for each zone to reopen.

Before we start on site

  • Warn occupants and staff about the work
  • Share your working hours and any access restrictions
  • Make sure the joints can be reached

Request a quote

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Advice

Work for main contractors and building owners

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Worn screed or surface finishes
  • Structural cracking in the slab
  • A floor that rocks at the joints, which needs a structural fix

If you are not sure, just speak to us on 01277 525 020 or use the quote form and we will give you a straight answer before you book.

Where we work in Farnham

FAQs: Farnham

Is Farnham too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Is Birchanger Industrial Estate, near Farnham, within your area?

Yes. Our area takes in Farnham and its surroundings, with estates and business parks such as Birchanger Industrial Estate included. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.

Can the sealant be colour-matched?

It depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Is it normal for joint filler to separate?

It can be shrinkage, contamination on the joint faces or a product unsuited to the movement. We look at which it is before recommending anything.

What information helps you price floor joint sealing?

Approximate metres of joint, photos of typical and worst areas, and a floor plan are usually enough for a quick quote. We can visit where that helps, and you can speak to us on 01277 525 020 or send photos by email to arrange it.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
