Facade sealing for Chapel Row sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

When to call us in Chapel Row

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

Common reasons buildings call us in:

  • Weathered joints at frame-to-structure perimeters
  • Leaks at window and door perimeters
  • Patch repairs that keep failing
  • Staining on stone next to old sealant

With historic properties like Horselunges Manor, 3.4 miles to the west of Chapel Row, in the area, refurbishment work often meets old masonry that needs compatible sealants.

Questions to ask before you book

  • Can the work be phased to keep areas open?
  • Who will actually carry out the work
  • How the existing material will be dealt with
  • Proof of insurance

Our contractor checklist

About our facade sealing in Chapel Row

External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. We work on perimeter joints where frames meet the structure, coping and flashing joints and cladding panel joints, and the failures we are asked to look at most are unsightly perimeter sealant on a visible elevation and facade joints cracked through the middle. For commercial sealant work in Chapel Row, you deal with one contact from quote to sign-off, whether it’s one building or several.

Sites around smaller places like Chapel Row can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photographs and the programme and we’ll quote to suit.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Building and refurbishing in Chapel Row

Chapel Row is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager. At about 46 miles from central London, Chapel Row is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes.

New wings at hospitals like Amberstone Hospital, 2.2 miles to the west of Chapel Row, bring long runs of window and panel joints to seal. Projects at schools like Herstmonceux Church of England Primary School work to term dates, so mastic is programmed tightly.

Chapel Row is about 3 miles north-east of Hailsham, in East Sussex. We cover commercial sites throughout Chapel Row. Chapel Row is one of 308 places in East Sussex on our list for facade joints. For work in that direction, see our Brighton page.

Anyone looking for facade sealing in BN27 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. Nearby places we also cover include Flowers Green (1 mile south), Herstmonceux (1 mile north-west), Windmill Hill (1 mile east), Golden Cross (1 mile south-west) and Stunts Green (1 mile north-west). Bigger towns within reach include Eastbourne (7 miles south), Hastings (10 miles east), Bexhill-on-Sea (7 miles south-east), Seaford (12 miles south-west), Lewes (14 miles west) and Hailsham (3 miles south-west).

Site staff or a sealant specialist?

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

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

Why it’s worth doing now in Chapel Row

Failed joints let in more than water: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. Around Chapel Row, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

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 we will put a fixed figure on it.

What you get with us

  • A fixed quote before work starts
  • Specification-led, product-correct work
  • Our applicators hold CSCS cards
  • RAL and finish matching where the product range allows

Take a look at what affects the cost or how we’re accredited.

Surface by surface

Render and coated surfaces

Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.

Brick and stone facades

Stone can absorb plasticisers from the wrong sealant. The specified stone-compatible sealant is what we use.

How a job runs

At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Chapel Row are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

What we need from you

  • Let us know about inductions and permits
  • Point out any areas we must not close
  • Share your working hours and any access restrictions

Ask for a quote

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

After the work

Problems stay small when the joints are checked regularly. Specifically:

  • Check that rainwater leaves the facade the way it was designed to
  • Record the product and colour used on each elevation
  • Insist on a full cut-out when joints are renewed
  • Plan facade sealing alongside redecoration

Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.

Coordinate facade sealing with other external works. Sharing the access keeps the cost down.

FAQs: Chapel Row

Is Chapel Row too far out for you?

No. Places such as Chapel Row are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Can you keep pace with our programme in Chapel Row?

Yes. The mastic is planned around your key stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

What site paperwork can you supply?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Is the work guaranteed?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Are you fully insured?

Yes. Mastic Doctor is fully insured, public liability included.
