Contractors’ notes for Bentley

Bentley sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. Central London is about 18 miles from Bentley. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.

For contractors at a college like Havering Technical College, 2.7 miles south-west of Bentley, perimeters and internal sealant are timed for the holidays. On a healthcare site such as Nuffield Hospital, 2.7 miles south-east of Bentley, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Bentley is about 2 miles north-west of Brentwood, in Essex. Our applicators travel to Bentley for work on facade joints. Our Essex coverage takes in 644 places, large and small. Our London page has more on work in that area, about 18 miles away.

About our facade sealing in Bentley

Water ingress at window frames is a frequent reason facilities managers contact us. Very often the perimeter bead has cracked or lost its grip, but not always. If the evidence points away from the sealant, we say so before quoting. If you are dealing with discoloured or dirty facade joints and sealant pulling away from frames or panels, we can help. Most enquiries from Bentley start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Construction in and around smaller places such as Bentley is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

On site: what to expect

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Rural sites near Bentley may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Getting the site ready

  • Let building users know which areas are affected
  • Have the specification and drawings to hand
  • Send your site hours and access windows

Getting a fixed quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Record the product and colour used on each elevation
  • Ask about asbestos in pre-2000 mastic
  • Add perimeter sealant to planned maintenance checks
  • Check that rainwater leaves the facade the way it was designed to

Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.

Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Honest limits

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Movement beyond what any sealant can handle
  • Render or concrete edges that have broken away
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

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

Surfaces we seal

  • Shopfront frames
  • Cladding panel joints
  • Coping and flashing joints
  • Stone and brick facade joints
  • Window and door perimeters
  • Perimeter joints where frames meet the structure

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Owners, agents and contractors

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

Building owners and managing agents use us on everything from one building to a spread of sites around Bentley. One quote can cover more than one site, which keeps the paperwork simple.

Do you need facade sealing in Bentley?

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

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

  • New sealant peeling off old mastic
  • Leaks at window and door perimeters
  • Air leaks through failed facade joints
  • Perimeter joints where frames meet the structure

When a school such as Becket Keys Church of England School is extended or refurbished, the mastic package is often squeezed into the holidays.

What to look for in a quote

  • Whether primer will be used where the manufacturer specifies it
  • Will CSCS-carded applicators be on site?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Which product they’ll use, and why it suits the joint

Choosing a commercial sealant contractor

Bentley: questions and answers

Can you work around term dates at a campus such as Havering Technical College?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Do you take on work at healthcare sites like Nuffield Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

How is access to upper-level joints handled?

That comes down to the access arranged for the job. Share what access exists or is planned when you send details.

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

Will you just go over the old sealant?

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

How long does a job like this take?

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