Commercial sealant contractors near Leeds

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

Honest limits

Being straight saves everyone time. New sealant won’t cure:

  • Broken glass or blown double-glazed units
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)
  • Water from a services leak rather than a joint

If you’re not sure, just speak to us on 01277 525 020 or email us and we will give you a straight answer.

What we seal

  • Kitchen worktops and splashbacks
  • Floor and threshold joints
  • External facade joints
  • Window and door perimeters
  • Washrooms and tea points
  • Movement joints in walls and floors

Sealant specialists in Leeds

Pricing a commercial reseal is a short process. Send photographs, drawings or a schedule of the joints through our quote form and you can also ring 01277 525 020 or send details through our quote form to talk it through. If the joints need seeing in person, a site visit comes first, followed by a fixed quote rather than an estimate that drifts. If you’re dealing with black mould through washroom sealant that won’t clean off and frame sealant that has cracked, shrunk or pulled away, we can help, on washrooms and tea points, movement joints in walls and floors and window and door perimeters alike. Whoever orders the work in Leeds, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

If you look after more than one building near Leeds, the work can be planned as one programme, so standards and paperwork match across every site.

Work in smaller places such as Leeds tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

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’re clear about what is covered before work starts.

How the job changes by surface

Washrooms and toilets

Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. Old sealant comes out and a sanitary silicone with anti-mould additives goes in, phasing the rooms so not every toilet is closed at once.

Movement joints in walls and floors

A trafficked floor joint needs a different product from a wall joint. We’ll recommend the right filler or sealant for the traffic and movement, and tell you if the edges need repairing first.

Questions we’re asked in Leeds

Do you cover business parks and estates near Leeds, such as Park Wood Trading Estate?

Yes. We cover Leeds and the area around it, including industrial estates, business parks and retail parks such as Park Wood Trading Estate. Send details of the unit and the work through our quote form for a quick quote.

Is a smaller place like Leeds outside your area?

No. Places such as Leeds are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Which site documents can you send us?

Send your site requirements with the enquiry, and we will confirm the RAMS, insurance and CSCS details with the quote. From you, we’ll need the asbestos information for older buildings and any site rules.

Does commercial sealant work come with a guarantee?

It’s backed by our 12-month guarantee. Should a joint we sealed give trouble during those 12 months, let us know and we will look at it.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

How many days will you need on site?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Work for main contractors and building owners

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.

Doing it in-house

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Sealant on show in Leeds’s commercial buildings

At least three named trading, business or retail sites lie within about 3 miles of Leeds. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints; brand colours often come into it. Leeds is about 35 miles from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Firms with branches across the South East can use one contractor for every site.

Occupiers with premises at both Park Wood Trading Estate and Orchard Industrial Estate could have the sealant at each handled under one quote. Industrial estates such as Park Wood Trading Estate, 1.9 miles west of Leeds, have offices, trade counters and welfare areas whose sealant ages like any other building’s. Shops and cafés around stations like Hollingbourne station, 1.6 miles north-east of Leeds, trade from early, so work is timed around them.

How the quote is worked out

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Induction, permit and paperwork requirements
  • Which sealant the job calls for
  • The total length or number of joints
  • Whether old sealant has to be cut out first

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 quote.

What we need to price the job

Diagnosis starts before we arrive. Let us know:

  • Photos of the joints, close up and from further back
  • Anything awkward about access or site hours
  • The product your specification calls for
  • Rough lengths or quantities, or drawings if you have them

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

On site: what to expect

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes a few hours for one area, or a planned series of visits across a bigger building, and our waste is bagged and taken away as we go. Rural sites near Leeds may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Before we start on site

  • Flag any permit to work we’ll need
  • Warn occupants and staff about the work
  • Confirm the product named in the specification
