Facade sealing in Benington: the local picture

Benington is about 27 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. Benington is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack.

For contractors at a school such as Benington Church of England Primary School, sealing has to be finished before term starts. On a healthcare site such as Lister Hospital (4.8 miles north-west of Benington), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Benington is about 3 miles east of Stevenage, in Hertfordshire. Businesses, contractors and managing agents in Benington can call on us for facade joints. Benington is one of 371 places in Hertfordshire on our list for facade joints. Sites around London have their own page, about 27 miles away.

About our facade sealing in Benington

A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear with the ratio the sealant maker recommends, often around 2:1. If you’re dealing with sealant pulling away from frames or panels and damp patches beside frames after rain, we can put it right, on shopfront frames, coping and flashing joints and cladding panel joints alike. Searching for sealant specialists in Benington? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

In the countryside around places like Benington, 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.

Work we carry out in Hertfordshire comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or email the details over and we’ll come back to it.

What we are called out for in Benington

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:

  • Perimeter sealant that has split or peeled away
  • Perimeter joints where frames meet the structure
  • Previous reseals run over old sealant
  • Cladding panel joints that have opened up

Older buildings in the area around Benington, such as Aston Bury, 2 miles south-west of Benington, need care when sealed: the product has to suit soft or historic materials.

Questions to ask before you book

  • How they handle RAMS and site documents
  • What the guarantee covers, and for how long
  • Do they follow the manufacturer’s priming guidance?
  • Who will actually carry out the work

Choosing a commercial sealant contractor

Surface by surface

Window and door perimeters

Frames grow and shrink with temperature, and the perimeter joint has to follow. The rod limits depth, leaving the bead able to flex as the frame moves.

Brick and stone facades

Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one, with masked edges for a clean line.

Work for main contractors and building owners

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Benington can sit alongside others in a wider programme across Hertfordshire.

Our process

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Jobs in and around smaller places like Benington are normally planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Share the asbestos register for older buildings
  • Make sure the joints can be reached
  • Arrange parking or a loading space

Questions we are asked in Benington

Is Astonbury Farm & Business Park, near Benington, within your area?

Yes. We cover Benington and the area around it, including industrial estates, business parks and retail parks such as Astonbury Farm & Business Park. To start, just ring 01277 525 020 or email the details over with the unit, the joints involved and your access times.

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

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Can you handle several sites?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Should we check old sealant for asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first. Removal of asbestos isn’t something we do.

Can you quote from photographs?

It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs usually get a visit.

Do you replace windows or glass?

No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, including perimeters where frames meet the structure.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Why it’s worth doing now in Benington

Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Leaks travel along the structure. Older rural buildings around Benington move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.
