About our commercial sealant contractors in Corhampton

On a commercial site, sealant turns up in more places than people expect: around sanitaryware, along worktops and splashbacks, at window boards, partition heads and floor junctions. Outside, it closes facade joints, frame perimeters and movement joints against the weather. Our applicators work on both the inside and the outside of the building. If you are dealing with expansion joints with the sealant torn out and smeared sealant across finishes from a rushed job, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Corhampton, preparation and product choice get the time they need.

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

Rural business units near smaller places such as Corhampton are frequently converted agricultural buildings. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Common problems we fix in Corhampton

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. It’s one of the commonest faults we find on earlier work.

Common reasons buildings call us in:

  • Movement joints packed with grit and debris
  • Leaks that seem to come through a sealant line
  • Mouldy silicone around WCs, urinals and vanity tops
  • Greasy, split joints in a kitchen or tea point

Colour matters on frontages and fit-outs, so the quote confirms which colours the chosen product comes in.

Comparing quotes

  • Whether their applicators hold CSCS cards
  • Health and safety accreditation such as CHAS
  • How the existing material will be dealt with
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

How to choose a sealant contractor

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For a building around Corhampton, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  2. A fixed quote follows, with removal and preparation included.
  3. We agree the order of work, access windows and site hours with you.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. Completed areas are signed off with you under our 12-month guarantee.

Preparing the site

  • Tell staff and tenants when we’ll be in
  • Send asbestos survey details if the building is pre-2000
  • Clear stock, furniture or equipment away from the joints

Advice

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:

  • Structural cracks or movement the joints weren’t designed for
  • Leaks from pipework, wastes or valves (that’s plumbing)
  • A failed roof covering or waterproofing membrane

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

What we seal

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

FAQs: Corhampton

What paperwork can you provide for a job in Corhampton?

Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Is Corhampton too far out for you?

Not at all. Corhampton is within our area. 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.

What do you need from us to quote?

Send what you have, even a few photos and rough lengths. Questions or a site visit follow where needed, then a fixed quote.

Do you check for asbestos before removing sealant?

In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before disturbing old sealant, and if something is suspected, work stops until it’s tested.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Does commercial sealant work come with a guarantee?

Our workmanship is guaranteed for 12 months. Public liability insurance is in place too.

Can you take on work for an FM or managing agent?

Yes, and through main contractors too. You send the details, we return a fixed quote, and the job is done and signed off, with a 12-month guarantee on the workmanship.

Why act early in Corhampton

Spot repairs have their place. If the rest of the bead is the same age and product, though, it’s normally close behind. Where it helps, we quote a patch and a full reseal side by side. Converted and older buildings near places like Corhampton tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Why clients in Corhampton choose us

  • Colour options checked against the specified product
  • One phone line for London, the South East and Scotland
  • CHAS accredited contractor
  • Specification-led, product-correct work

See our cost guide or how we’re accredited.

General trades versus a specialist

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Cost factors for sealant joints

The price varies from site to site. Expect it to depend on:

  • Access and working height
  • Travel to remote or island sites
  • Quantities, in metres or numbers
  • Removal of failed or old sealant

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Details that help us quote

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

  • The asbestos register, for older buildings
  • Photos of the joints, close up and from further back
  • Your programme or deadline
  • Any specification or named product

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or send photos by email if you’d rather talk the job through.
