Commercial sealant contractors in Stroud, done properly

On a commercial site, sealant turns up in more places than people expect: washroom fittings, kitchen worktops, window boards, partition heads and the line where floors meet walls. Externally it keeps rain out of frame perimeters, panel joints and movement joints. Our applicators work on both the inside and the outside of the building, picking the product for each location rather than one tube for everything. We work on washrooms and tea points, external facade joints and floor and threshold joints, and what we are called in for most is shrunken sealant along kitchen worktops and splashbacks and untidy joints in a reception, shop floor or lobby. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Stroud, preparation and product choice get the time they need.

Occupied buildings in Stroud need the work phased: washrooms in turn, floors in sections and entrances kept open.

A job in a smaller place like Stroud is normally a single building. We will want a full list and photos first, so the right products come on the day and nothing waits for a second trip.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Stroud: questions and answers

Can you supply sealant in our brand colour for a site in Stroud?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.

Is Stroud too far out for you?

No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Does commercial sealant work come with a guarantee?

Our workmanship on each job is backed by a 12-month guarantee. We are fully insured for public liability as well.

Are you CHAS accredited and on Constructionline?

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

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators.

Which site documents can you send us?

Send your site requirements with the enquiry, and the paperwork is confirmed with the quote. For older buildings we’ll ask for the asbestos register, plus your site induction rules.

How long does a job like this take?

That varies with the scale of the job, but the work normally takes anything from part of a day on a short run of joints to several weeks on a large phased package. For bigger or phased jobs, we’ll set out a timescale with the quote.

Cost factors for sealant joints

Quotes vary with the job. It mainly depends on:

  • Removal of failed or old sealant
  • Backing rod, priming and other preparation
  • Working within restricted access windows
  • Travel to remote or island sites

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Before you send an enquiry

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

  • How the joints are reached, and at what height
  • The asbestos register, for older buildings
  • When you need the work done
  • Specification clauses that apply

For a fixed quote, call 01277 525 020 or send details through our quote form, telling us the site location and the nature of the job. Our quote form is another easy route.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Structural cracks or movement the joints weren’t designed for
  • Misted, cracked or failed glazing units (a glazier’s job)

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

Surfaces we seal

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

Keeping the joints sound

Cleaning and maintenance staff play a part too. Share these points with them:

  • Respect the cure time before reopening an area
  • Make sure ventilation in wet areas is switched on and working
  • Log reseals in the O&M or maintenance records
  • Act on the first lifting edges rather than waiting

Keep an eye out for other trades after we have gone. Shop refits, new services and replaced fittings often break the seal around them. Where work has disturbed a joint, just call the office on 01277 525 020 or send details through our quote form for a quote.

Sealant installed at the same time usually fails in sequence. A few splits this year typically mean more next year, so it makes sense to look at the wider elevation or block. We’ll tell you which sealant joints need doing first and which can wait.

How a job runs

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking a few hours for one area, or a planned series of visits across a bigger building. For work around Stroud, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. Send details through our quote form, or ask for a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Where parts of the building must stay open, the work is phased.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Getting the site ready

  • Confirm the product named in the specification
  • Point out any areas we must not close
  • Tell us what induction or permit system the site runs

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or email the details over.

Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme, and the work can be phased so the rest of the hotel keeps trading. Stroud lies roughly 51 miles out from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Multi-site occupiers here often want one sealant contractor across all their buildings.

Premises within reach of Petersfield station (to the east of Stroud) often have busy frontages where joints are seen by everyone passing.

What happens if it’s left?

Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. Often the fitting is sound and the joint is the only thing letting it down. Resealing typically costs far less than renewal. Older rural buildings around Stroud move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.

What you get with us

  • 12 months’ guarantee on every job
  • CHAS accredited
  • Coloured sealants to suit the setting, where available

Do you need commercial sealant contractors in Stroud?

If only one face has lost its grip, that’s an adhesion failure. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. We see it often where joints were sealed in a hurry.

Typical triggers for a call:

  • Weathered facade sealant that no longer flexes
  • Greasy, split joints in a kitchen or tea point
  • Water staining near frames, panels or ceilings
  • Expansion joints with the sealant torn out

Whatever the building in Stroud, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.

What your quote should include

  • How they’ll work around occupants
  • Will failed sealant be removed rather than covered?
  • How joint depth will be controlled
  • Do they follow the manufacturer’s priming guidance?
