Floor joint sealing in Alderholt

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

Floor joint sealing in Alderholt

Some joints reach us with their edges already broken. A filler laid against broken edges has nothing sound to grip, so we will tell you if the joint edges need repairing first and explain how it affects the programme. We work on saw-cut induced joints, forklift and pallet-truck routes and construction joints, and the usual reasons a site gets in touch are filler that has parted from one face and old filler gone hard, cracked or loose. Searching for sealant specialists in Alderholt? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Small units near places like Alderholt are often converted farm buildings with new concrete floors. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.

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 are clear about what is covered before work starts.

FAQs: Alderholt

Will you take on work at estates like Fordingbridge Business Park, close to Alderholt?

Yes, sites like Fordingbridge Business Park are within our area, along with the rest of Alderholt. A few photographs and the unit address let us price the work.

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

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Do you repair broken joint edges?

We check the edges as part of the survey. Damaged edges are flagged up front, so nothing is filled that won’t hold.

Can the sealant be colour-matched?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

General trades versus a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Floor joint sealing around Alderholt: points for this area

The 3 miles around Alderholt take in at least three named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Alderholt is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, while winter salting gets into any joint left open.

For a school such as St James' Church of England First School, playground and building joints can be done in the holidays. Large sites such as Fordingbridge Hospital (to the north-east of Alderholt) have car parks, service roads and long elevations with movement joints in brick and panels. Office parks like Fordingbridge Business Park (1.4 miles north-east of Alderholt) have decks, ramps and clad elevations whose joints take movement every day.

Surface by surface

Saw-cut induced joints

A sawn joint left open soon packs with debris and chips at the edges. Filling them early keeps them tidy and protects the edges.

Isolation joints at walls and columns

Isolation joints separate the slab from walls, columns and plinths so it can move independently. A flexible product suits them better than a stiff filler.

What affects the price in Alderholt

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Whether old sealant has to be cut out first
  • Travel to remote or island sites
  • Site requirements such as inductions and permits
  • Backing rod, priming and other preparation

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Sending details for a quote

A few photos plus some basic facts will normally do. It helps to include:

  • When you need the work done
  • Asbestos survey details if the building is older
  • Drawings or a marked-up plan, if available
  • Specification clauses that apply

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or use the quote form.

After the work

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Hold traffic back until the product has cured
  • Let us know what the floor is cleaned with
  • Treat loading bay joints first if they’re failing
  • Keep grit out of unfilled joints in the meantime

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.

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

Why it’s worth doing now in Alderholt

Painting or coating straight over joints rarely lasts. Joints need their own treatment, whether or not the floor is coated. For buildings in places like Alderholt, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What you get with us

  • CHAS accredited
  • Clear, fixed quotes
  • Joints cleaned back to sound surfaces
  • Workmanship guaranteed for 12 months

From enquiry to sign-off

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a job in Alderholt, the main thing is a clear picture of the work. A fixed quote follows.

  1. We look at joint widths, edge condition and the traffic on each route.
  2. A fixed quote follows, listing the treatment for each area and the order of work.
  3. Old filler, debris and contamination are cut or routed out back to clean concrete.
  4. Dust is extracted from the joint and primer applied where the manufacturer specifies it.
  5. The chosen product is placed to its specified depth and trimmed level with the floor.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

Preparing the site

  • Flag any permit to work we’ll need
  • Share your working hours and any access restrictions
