Commercial sealant contractors for commercial buildings in Wraysbury

We’ve applied sealant on commercial sites for over 20 years, and the documents buyers ask for are ready: we’re CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. If your site needs RAMS, an insurance certificate or CSCS details, say so and we will confirm with the quote. We work on kitchen worktops and splashbacks, window and door perimeters and movement joints in walls and floors, and the usual reasons a site gets in touch are sanitary sealant that has gone black and patchy and external beads that have gone brittle and cracked. A specialist sealant contractor works differently from a general builder: on jobs in Wraysbury, preparation and product choice get the time they need.

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

Small businesses near places like Wraysbury frequently occupy converted farm buildings. Old masonry and timber meet new glazing and partitions in these buildings, and every junction needs a sealant that suits it.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Common problems we fix in Wraysbury

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.

Any of the following is a good reason to get the joints checked over:

  • Wall and floor joints that have lost their seal
  • Layers of sealant, all of them failing
  • Frame sealant that has cracked, shrunk or pulled away
  • Smeared sealant across finishes from a rushed job

On a business park such as Portland Business Park (1.8 miles north-west of Wraysbury), sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.

Choosing a commercial sealant contractor

Work for main contractors and building owners

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Your questions answered

Can you work at a site such as Portland Business Park, by Wraysbury?

Yes. We cover Wraysbury and the area around it, including industrial estates, business parks and retail parks such as Portland Business Park. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Is Wraysbury off your patch?

No. Places such as Wraysbury are covered as much as the big towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

How do we get a quote?

Send photographs, drawings or a list of locations through the quote form on this site. Where we need to see it, we’ll arrange a site visit, then send a fixed quote.

Is failed sealant stripped out, or sealed over?

Removal comes first, every time. After that come cleaning, primer where needed, backing and the new sealant.

Do you hold CHAS accreditation?

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

Does commercial sealant work come with a guarantee?

It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a job in Wraysbury, the main thing is a clear picture of the work. A fixed quote follows.

  1. We begin with whatever information you have, whether that’s photos, 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. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. Finished joints are checked with you and handed over with our 12-month guarantee.

Before we start on site

  • Warn occupants and staff about the work
  • Flag any permit to work we will need
  • Send your site hours and access windows

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

How the job changes by surface

Fire-rated seals where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. Fire-stopping design and sign-off sit with the designer, fire engineer or building control.

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.

When it isn’t the sealant

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:

  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Roof leaks that only look like a joint problem

If in doubt, call 01277 525 020 or email the details over and we will say what we think.

Where we work in Wraysbury

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

Keeping the joints sound

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

  • Have extract fans checked so wet areas dry out
  • Report cracked or peeling sealant early
  • Keep a record of which joints were resealed and when
  • Ask fit-out and M&E contractors to report any sealant they disturb

Good ventilation keeps wet-area sealant in better condition. Fans that are broken or switched off leave joints damp for longer. It’s worth having fans checked while the sealant is fresh.

Occupiers often notice failing sealant before the facilities team does. Replacing it on a planned cycle keeps complaints down.

What Wraysbury’s businesses ask us to seal

At about 20 miles from central London, Wraysbury is within reach of the capital. Business parks and retail centres are common around the capital’s motorway corridors. If you have premises across the region, one contractor can cover them all. Wraysbury is in the South East, one of the UK’s drier regions. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

Sites a few miles apart, such as Portland Business Park and The Green Business Centre, can share one programme and one point of contact. Shops and cafés around stations like Sunnymeads station (0.8 miles north of Wraysbury) trade from early, so work is timed around them.
