Floor joint sealing in Winchester

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

How we handle floor joint sealing in Winchester

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. If you’re dealing with loading bay joints breaking down and joint fill separating from the concrete, we can put it right. Facilities teams, main contractors and managing agents in Winchester tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Work on floor and movement joints in a large place such as Winchester is normally phased: aisle by aisle or deck by deck.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Site staff or a sealant specialist?

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Our process

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes anything from a day for one loading bay to several days for a large floor, split into phases, and our waste is bagged and taken away as we go. Town-centre jobs in Winchester can mean limited parking and loading, while out-of-town estates normally have yards and car parks. Let us know what’s there when you send details.

  1. First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
  2. A fixed quote follows, listing the treatment for each area and the order of work.
  3. We remove failed material and packed debris until sound concrete is exposed on both faces.
  4. Dust is extracted from the joint and primer applied where the manufacturer specifies it.
  5. Filler or sealant goes in to the right depth and is finished flush with the slab.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

Getting the site ready

  • Tell staff and tenants when we will be in
  • Agree which areas must stay open
  • Send your site hours and access windows

Getting a fixed quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Advice

FAQs: Winchester

Is Bar End Industrial Estate, near Winchester, within your area?

Yes. Our area takes in Winchester and its surroundings, with estates and business parks such as Bar End Industrial Estate included. A few photographs and the unit address let us price the work.

Must our site in Winchester stop work while the joints are done?

Rarely. Work is phased around your operations. The phasing plan comes with the quote.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

How long does a job like this take?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Do you cover Winchester?

Yes. We take on work across Winchester, with one number for every area we cover.

Why it’s worth doing now in Winchester

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. A leaking joint in a commercial building in Winchester can damage stock, ceilings and finishes. It’s worth fixing at the first sign.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

  • Fully insured
  • CHAS accredited contractor
  • Work to your specification and the manufacturer’s guidance
  • Over 20 years of commercial sealing

Traffic, movement and joints around Winchester

Rainfall across the South East, Winchester included, is lower than in many parts of the UK. 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. At least three named trading, business or retail sites lie within about 3 miles of Winchester. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Retail centres such as Moorside Retail Park, 1.1 miles to the north-east of Winchester, have floors, service yards and car parks with joints under constant traffic. On industrial estates such as Bar End Industrial Estate, 0.6 miles to the south-east of Winchester, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. Hospitals like Royal Hampshire County Hospital (to the west of Winchester) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Winchester is in Hampshire. We send applicators to Winchester for floor joints. Winchester is one of 723 places in Hampshire on our list for floor joints. For work in that direction, see our Southampton page, about 10 miles away.

Commercial sites across SO22, SO23, SO32 and SO21 are covered. We cover commercial and managed buildings on The Square, Market Street and Market Lane. You will find Winchester on or near the A31 and A32. If your building is just outside Winchester, we cover Bar End (1 mile south-east), Highcliffe (1 mile east), Hyde (1 mile north), St Cross (1 mile south) and Stanmore (1 mile south-west).

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • Whether the work must be split into stages
  • Backing rod, priming and other preparation
  • Site requirements such as inductions and permits
  • The total length or number of joints

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

What to include in your enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • Rough lengths or quantities, or drawings if you have them
  • The type of building and who uses it
  • The asbestos register, for older buildings
  • Your programme or deadline

Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. If you have questions first, ring 01277 525 020 or use the quote form.

Looking after the joints

Problems stay small when the joints are checked regularly. In particular:

  • Allow for topping up joints as a new slab settles
  • Sweep debris out of open joints until they can be filled
  • Photograph any joint that starts to chip
  • Make joint checks part of your floor inspections

Ask drivers not to drag forks or pallets along the floor. Steel tines will mark a good joint over time if it keeps happening.

While the concrete edges are intact, it’s a filling job. Once they have broken away, edge repair comes first, with more downtime and more disruption.
