About our facade sealing in Kent Street

Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. We work on stone and brick facade joints, window and door perimeters and perimeter joints where frames meet the structure, and what we’re called in for most is sealant pulling away from frames or panels and failed sealant on precast panel joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Kent Street, preparation and product choice get the time they need.

In the countryside around places like Kent Street, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What the job involves on each surface

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building.

Brick and stone facades

Stone can absorb plasticisers from the wrong sealant. The specified stone-compatible sealant is what we use, and mask the edges carefully.

Contractors’ notes for Kent Street

Central London is about 49 miles from Kent Street. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes. There are several hotels within about 2 miles of Kent Street. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.

Older buildings in the area around Kent Street, such as Durhamford Manor, 2.2 miles to the north-west of Kent Street, need care when sealed: the product has to suit soft or historic materials. For a contractor working at a hospital such as Conquest Hospital (2.2 miles south-east of Kent Street), perimeter and facade sealing is planned around patients and deliveries.

Kent Street is about 3 miles north of Hastings, in East Sussex. We cover Kent Street and the rest of East Sussex, with the same fixed quotes and 12-month guarantee as everywhere else. Across East Sussex, 308 places are covered, including Kent Street. Brighton is covered too, some 30 miles away.

Business premises anywhere in TN33 are within our area for facade joints. Sites close to Kent Street are covered too, including Westfield (1 mile east), Telham (2 miles west), Sedlescombe (2 miles north), Whatlington (2 miles north-west) and Brede (3 miles north-east). Bigger towns within reach include Eastbourne (14 miles south-west), Hastings (3 miles south), Bexhill-on-Sea (6 miles south-west), Hailsham (13 miles west), St Leonards (4 miles south) and Polegate (14 miles south-west).

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Jobs in and around smaller places like Kent Street are usually planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

Before we start on site

  • Flag any permit to work we’ll need
  • Have the specification and drawings to hand
  • Point out any areas we must not close

Advice

What happens if it’s left?

Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. One visit to deal with every failing joint makes more sense than several trips to a place like Kent Street. Photos of every joint help us quote for the whole job.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Why us?

  • Health and safety: CHAS accredited
  • RAL and finish matching where the product range allows
  • Fully insured, including public liability cover
  • Colour agreed before work starts

See what affects the cost or how we’re accredited.

Do you need facade sealing in Kent Street?

Sometimes the substrate is the problem: if the edge of the render, concrete or coating breaks away, the bead goes with it. When the joint edges need repair first, we say so.

Common reasons buildings call us in:

  • Weathered facade joints that have lost their grip
  • Leaks at window and door perimeters
  • Patch repairs that keep failing
  • Failed sealant on precast panel joints

For a contractor at a hotel such as Claverton Country House Hotel (under half a mile south of Kent Street), the mastic often has to be finished before a reopening date.

Questions to ask before you book

  • Is the sealant right for the movement and the substrate?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How long is the guarantee, and what does it include?
  • How they’ll work around occupants

Questions to ask before you appoint anyone

Maintenance after handover

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Avoid harsh cleaners on facade sealant
  • Plan facade sealing alongside redecoration
  • Keep the sealant details on the building file
  • Don’t wait for a second leak before calling

Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed instead of soaking the joints.

Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.

Kent Street: questions and answers

Is a hospital such as Conquest Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Is Kent Street too small for you to travel to?

Not at all. Kent Street is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Will you check whether the sealant is causing the leak?

Yes. We look at the perimeter sealant and tell you whether it has failed. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How long does a typical visit take?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Cost factors for facade joints

The price varies from site to site. It mainly depends on:

  • Location, for remote and island sites
  • Joint width, depth and condition
  • Phasing around occupants
  • The site’s rules and procedures

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Details that help us quote

To price the job accurately, we need to understand the site. Useful things to include:

  • Whether the building will be occupied during the work
  • Asbestos survey details if the building is older
  • How the joints are reached, and at what height
  • Any dates the work must fit around

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, ring 01277 525 020 or send photos by email.
