Expansion joint sealing across Firgo

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

What happens if it’s left?

Resealing is usually the answer, not replacing the element. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we’ll tell you they need repairing first. One visit to deal with every failing joint makes more sense than several trips to a place like Firgo. Photos of every joint help us quote for the whole job.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Why clients in Firgo choose us

  • Products installed to the manufacturer’s instructions
  • Colours chosen to suit frames, cladding or finishes where possible
  • CSCS-carded applicators
  • A Constructionline member, so easy to vet

About our expansion joint sealing in Firgo

Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. If you are dealing with torn sealant in brick or block movement joints and debris jammed in movement joints, we can put it right, whatever the surface. Most enquiries from Firgo start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Jobs around smaller places like Firgo are planned so the whole job is done in one visit. Note joint widths and the traffic that uses them, and we will take it from there.

A 12-month guarantee applies to all our work in Hampshire. If an installation problem shows up, call 01277 525 020 or send photos by email and we’ll arrange a return visit.

From enquiry to sign-off

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. If others near Firgo need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Preparing the site

  • Tell us which areas need to stay in use
  • Let us know about inductions and permits
  • Tell us your opening times and when work is allowed

Firgo: questions and answers

Is a smaller place like Firgo outside your area?

No. Places such as Firgo are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Do we have to stop operations in Firgo while the joints are sealed?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we’ll plan from there.

Do you offer coloured sealant?

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.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Can you fit around our working hours?

Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

Do you need to see the site first?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

What happens if it rains on the day?

Outside work depends on conditions: rain, frost and condensation all stop sealant bonding. Indoor joints can usually carry on regardless.

Joints that move: notes for Firgo

Central London is about 58 miles from Firgo. The South East has large numbers of industrial estates and warehouses along the motorway corridors. Firgo 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, and winter de-icing salt on car parks and ramps works into any open joint.

For an occupier at a site such as Ardglen Industrial Estate, 2.1 miles to the north of Firgo, the joints at loading doors and dock levellers usually see the hardest wear.

Firgo is about 6 miles east of Andover, in Hampshire. We cover Firgo and the rest of Hampshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 723 places across Hampshire fall within our area, including Firgo. We also cover Southampton, around 20 miles from Firgo.

Anyone looking for expansion joint sealing in RG28 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. If your building is just outside Firgo, we cover Hurstbourne Priors (2 miles north-west), Whitchurch (2 miles north), Wells-in-the-Field (2 miles north-east), Freefolk (3 miles north-east) and Cole Henley (4 miles north). Nearby towns on our patch include Basingstoke (11 miles north-east), Winchester (10 miles south), Andover (6 miles west), Chandler's Ford (15 miles south), Tadley (13 miles north-east) and Hyde (9 miles south).

Owners, agents and contractors

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

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Different surfaces, different methods

Podium joints

Podium decks are exposed and often trafficked. We choose a product that copes with feet, wheels and weather.

Car park decks and ramps

Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again, and we will tell you if any edges need repairing first.

What we’re called out for in Firgo

When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again, so we check width and movement before quoting.

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

  • Arrises breaking up along floor joints
  • Joints packed with grit and debris
  • Layers of sealant in a movement joint
  • Brittle, chalky sealant on external joints

In a school such as Testbourne Community School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Before you book anyone

  • Will failed sealant be removed rather than covered?
  • Their approach to joint depth and backing
  • Health and safety accreditation such as CHAS
  • How long is the guarantee, and what does it include?

Choosing a commercial sealant contractor

Quoting for work in Firgo

We price every job individually. The main factors are:

  • Working within restricted access windows
  • How much there is to seal
  • Whether old sealant has to be cut out first
  • Joint width, depth and condition

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Sending details for a quote

Good information means a firmer quote. When you get in touch, include:

  • Whether an asbestos survey exists
  • Any dates the work must fit around
  • Drawings or a marked-up plan, if available
  • Any specification or named product

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
