Commercial sealant contractors for Tyburn sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Why it’s worth doing now in Tyburn

On many buildings the mastic was done by whichever trade was on site. A specialist applicator takes care of product choice, joint depth and preparation. It shows over the following seasons rather than at handover. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.

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’ll put a fixed figure on it.

What you get with us

  • Sealing commercial buildings since 2005
  • Our applicators hold CSCS cards

  • Specification-led, product-correct work

How we handle commercial sealant contractors in Tyburn

How long a joint lasts is decided before any sealant leaves the gun. Silicone has no grip on cured silicone, so the failed bead is cut out completely and the faces are cleaned until they’re sound and dry, with no dust or grease left. Primer is used wherever the manufacturer calls for it on that surface. We work on external facade joints, kitchen worktops and splashbacks and window and door perimeters, and what we’re called in for most is a top-up bead over failed sealant, now lifting and smeared sealant across finishes from a rushed job. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Tyburn is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Multi-site clients with buildings in and around Tyburn can put several sites on one programme, so standards and paperwork match across every site.

For managing agents and FMs looking after premises in Tyburn, access is typically the first question: loading bay slots, goods lifts, permits to work and somewhere to keep materials. With access agreed, we work through the sealant joints a section at a time, keeping disruption to tenants low.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

How the quote is worked out

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

  • Travel to remote or island sites
  • Removal of failed or old sealant
  • Working within restricted access windows
  • Access and working height

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • Specification clauses that apply
  • Any dates the work must fit around
  • Where the site is, with the postcode
  • Rough lengths or quantities, or drawings if you have them

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or email the details over.

Surface by surface

Window and door perimeters

Internally, window boards and frame edges often have decorators’ caulk or silicone that has cracked. The product depends on whether the joint will be painted, matched to the frame colour where colour matters.

Fire-rated seals where specified

Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services and gaps, so we will flag it if the detail needs a different product.

Working on commercial sites near Tyburn

In London, commercial buildings often have managed loading bays, goods lifts and permit-to-work systems. We fit into those systems and phase the work so the building keeps operating. At least three named trading, business or retail sites lie within about 3 miles of Tyburn. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints, often in a colour the occupier specifies.

A hotel such as Parkwood Hotel (to the north-east of Tyburn) shows how much sealant a hospitality building has on show, from bathroom joints to the bar. If you look after units at a retail site such as Brompton Cross District Shopping Centre. (1.3 miles south of Tyburn), shopfront perimeters and shop-fit joints are where a matched colour shows. Offices and shops close to stations such as London Paddington station, 0.6 miles to the north-west of Tyburn, tend to be busy all day, so sealant work is planned around opening hours.

Tyburn is about 1 mile west of City of Westminster, in Greater London. Anywhere in W1H, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. 764 places across Greater London fall within our area, including Tyburn.

Business premises anywhere in W1H, W1U and W1K are within our area. For a building on Sussex Square, Oxford Square and Bayswater Road or nearby, send details and we’ll quote for sealant joints.

Nearby towns on our patch include London (3 miles east), Shoreditch (4 miles east), Walthamstow (8 miles north-east), Hoxton (4 miles north-east), Whitechapel (4 miles east) and Hampstead (3 miles north).

Tyburn: questions and answers

Do you take on jobs in Tyburn where loading and access are tightly controlled?

Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it

Will our hotel in Tyburn need to close for the work?

Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

What guarantee do you give on resealing?

Our workmanship on each job is backed by a 12-month guarantee. Public liability insurance is in place too.

Can you supply RAMS and insurance details?

We confirm documents at quote stage: RAMS, an insurance certificate and CSCS details are the usual requests. Our applicators are CSCS-carded.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited and a Constructionline member.

Honest limits

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Suspect materials that need testing and specialist removal
  • Broken glass or blown double-glazed units
  • Cracking that needs a structural engineer to look at it

If you’re not sure, just give us a call on 01277 525 020 or email the details over and we will give you a straight answer before you book.

Joints and surfaces we work on

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

Diagnose, treat, sign off

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Planning a London job such as one in Tyburn starts with access. Send the building rules and access times with your enquiry.

  1. Site photographs, 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. Sequence, access and working times are settled before the first joint is touched.
  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.

What we need from you

  • Have the specification and drawings to hand
  • Arrange parking or a loading space
  • Send your site hours and access windows
