About our floor joint sealing in Dormers Wells

Before quoting, we look at what the floor is telling us: joint widths, whether the joints are still opening, what runs over them and how the edges have held up. From that we choose between a semi-rigid filler and a more flexible sealant and the answer can differ from one zone to the next. If you are dealing with joint fill separating from the concrete and untidy open joints in a retail unit, we can put it right, on construction joints, forklift and pallet-truck routes and joints along racking aisles alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Dormers Wells it comes down to the same thing: the right product in a properly prepared joint.

Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. A failed joint lets water and debris in, and the edges soon spall.

The 12-month guarantee is for workmanship rather than 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.

What affects the price in Dormers Wells

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

  • Whether old sealant has to be cut out first
  • Distance, for remote addresses
  • Induction, permit and paperwork requirements
  • Phasing around occupants

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

Before you send an enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • Rough lengths or quantities, or drawings if you have them
  • Where the site is, with the postcode
  • Any specification or named product
  • A wide shot and a close-up of the area

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or email the details over to discuss it first.

When something else is needed

Honesty saves time and money. New sealant won’t cure:

  • Joint edges that have already broken away, which need repairing before filling (we will tell you if so)
  • A failing floor coating, which is a flooring contractor’s job
  • A floor that is out of level for the racking or trucks

Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we’ll tell you honestly.

Where we work in Dormers Wells

  • Saw-cut induced joints
  • Forklift and pallet-truck routes
  • Retail and showroom floors
  • Construction joints
  • Joints along racking aisles
  • Loading bays

Owners, agents and contractors

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

Common problems we fix in Dormers Wells

An ageing filler or sealant can go brittle and split, particularly where cleaning machines and traffic work it daily. At that point it neither holds the edges nor keeps debris out.

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

  • Old filler gone hard, cracked or loose
  • A rough ride across broken joints
  • Untidy open joints in a retail unit
  • Saw-cut joints left open and packed with grit

Phasing is what makes joint work possible on busy sites such as Great Western Industrial Park (0.6 miles south of Dormers Wells): one bay, aisle or car park row at a time.

Comparing quotes

  • How the joint faces will be prepared and primed
  • Will CSCS-carded applicators be on site?
  • Health and safety accreditation such as CHAS
  • Will failed sealant be removed rather than covered?

Our contractor checklist

After the work

Cleaning and maintenance staff play a part too. Share these points with them:

  • Plan for a top-up on newer floors
  • Photograph any joint that starts to chip
  • Sweep debris out of open joints until they can be filled
  • Keep trucks off new joints until we say they’re ready

Normal floor cleaning is fine once the product has cured. If you use strong chemicals or hot-water washing, mention it when we quote so the product suits them.

Every vehicle on a busy aisle hits a damaged joint. Sorting it early looks after your equipment as well as the slab.

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. We walk the floor and mark up joint widths, edge damage and traffic routes.
  2. The treatment and the zones are set out in a fixed quote.
  3. Old fill and packed debris come out until both faces are sound.
  4. Dust is vacuumed out and primer applied where specified.
  5. Filler or sealant is placed to depth and finished flush.
  6. We hand each phase back when it can take traffic.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Flag any permit to work we’ll need
  • Tell staff and tenants when we will be in

Questions we are asked in Dormers Wells

Do you work in London buildings with loading restrictions?

Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it

Will you take on work at estates like Barratt Industrial Estate, close to Dormers Wells?

Yes. Estates, retail parks and business parks around Dormers Wells, Barratt Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Is it normal for joint filler to separate?

On newer slabs, the concrete keeps shrinking after the joints are filled, so a semi-rigid filler can part from one face. It is normally dealt with by topping up.

Is colour matching possible?

It depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

How long does a job like this take?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

What information helps you price floor joint sealing?

Send details through our quote form or by email, with the traffic on each area. We then send a fixed quote that shows the products and zones.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.
