Floor joint sealing for businesses in Back

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

From enquiry to sign-off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes anything from a day for one loading bay to several days for a large floor, split into phases. Where we can, we combine work around Back with other jobs nearby. Tell us how flexible your dates are.

  1. We agree the traffic routes and phasing with your site team.
  2. Any joints with broken edges are flagged before work starts.
  3. We clear each run back to clean concrete.
  4. The chosen filler or sealant goes in flush with the slab.
  5. Each area is handed back when ready for traffic.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Clear stock, furniture or equipment away from the joints
  • Tell us which areas need to stay in use

About our floor joint sealing in Back

Few warehouses can shut a whole floor while joints are done, so we phase the work aisle by aisle or bay by bay. Tell us your site hours and access windows and we’ll plan around them so the rest of the operation keeps going. We work on construction joints, saw-cut induced joints and forklift and pallet-truck routes, and the usual reasons a site gets in touch are dock area joints that have failed first and flexible sealant torn out by wheels. One point of contact handles commercial sealant work in Back from the first photos to the final walk-round, for single jobs and planned programmes alike.

For floor or movement joints around smaller places like Back, we plan to finish in one visit where we can. Send photos, joint widths and details of the traffic first.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Traffic, movement and joints around Back

Back sits close to the coast, within about 1 mile. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so it pays to keep them sealed. For an island location such as Back, work is planned around ferry crossings and the weather. Approximate joint lengths and widths let us bring enough material first time.

Around Back, each joint gets a filler or sealant matched to what crosses it and how much it moves.

Back is about 6 miles north-east of Stornoway, in Na h-Eileanan Siar. We send applicators to Back for floor joints, handled exactly as we handle every other area. 87 places across Na h-Eileanan Siar fall within our area, Back among them.

Anyone looking for floor joint sealing in HS2 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. For a building on Broadbay View, Rathad na Sgoile and Sraid na H-Eaglaise or nearby, send details and we will quote for floor joints. Nearby places we also cover include Sulaisiadar (5 miles south-east), Garrabost (5 miles south-east), Na h-Eileanan an Iar (5 miles south), Knock (5 miles south) and Aiginis (5 miles south). For island and remote sites, we plan travel and materials carefully, so include the location in your enquiry.

Well-known places in the area include Western Isles Hospital (5.4 miles south-west). Open spaces near Back include Loch Langavat.

Why deal with it now?

Painting or coating straight over joints rarely lasts. Joints need their own treatment before or alongside any coating work. For buildings near Back, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.

There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

Why us?

  • Work carried out by CSCS-carded applicators
  • Work to your specification and the manufacturer’s guidance
  • Constructionline member for supplier checks
  • Fully insured

Questions we’re asked in Back

Can you take on a job in Back, on the island?

Yes. Islands are part of our area, Back included. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

Is a hospital such as Western Isles Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you send site paperwork?

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

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

What do you need from us to quote?

A rough joint length, a few photos and a site plan are typically enough for a quick quote. For larger floors, a site visit is often best so call the office on 01277 525 020 or use the quote form to set one up.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

Site staff or a sealant specialist?

Redoing a failed joint usually costs more than getting it right at the outset, 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.

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.

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • Uneven floors that need grinding or levelling
  • Worn screed or surface finishes
  • Wide or random cracking that suggests a structural issue

If you are not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Joints and surfaces we work on

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

When to call us in Back

Concrete slabs shrink as they dry out, and saw-cut joints give that shrinkage a planned place to crack. As the panels contract, the joints widen so a filler put in early may separate along one side.

If one of these sounds familiar, it’s time for a closer look:

  • Broken arrises where pallet trucks cross
  • Grimy joint lines spoiling a showroom floor
  • Saw-cut joints left open and packed with grit
  • Old filler gone hard, cracked or loose

Sites like Western Isles Hospital, 5.4 miles south-west of Back, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

What your quote should include

  • What the guarantee covers, and for how long
  • How joint depth will be controlled
  • Whether old or failed sealant will be cut out, not overlaid
  • Proof of insurance
