Facade sealing for Boreham Street sites

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

What sealant work can’t fix

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Water getting in through cracked render or porous masonry
  • Work on the window or framing system itself
  • Specialist high-level access methods

If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

What we seal

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

Facade sealing in Boreham Street, done properly

Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits, so frosty or damp mornings can hold work back. We build that into the programme and tell you if the forecast changes the plan. The enquiries we see most involve cold air coming in at window perimeters and failed seals around shopfront and entrance frames, across shopfront frames, window and door perimeters and perimeter joints where frames meet the structure. Whether you call it commercial sealant work, mastic application or joint sealing, in Boreham Street it comes down to the same thing: the right product in a properly prepared joint.

Around smaller places like Boreham Street, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Quoting for work in Boreham Street

To price the job, we consider:

  • Site requirements such as inductions and permits
  • Joint width, depth and condition
  • Access and working height
  • Which sealant the job calls for

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

What to include in your enquiry

A good diagnosis starts with the right details. Let us know:

  • Whether the building will be occupied during the work
  • Asbestos survey details if the building is older
  • Photos of the joints, close up and from further back
  • The product your specification calls for

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to speak to us on 01277 525 020 or email the details over with what you know.

How a job runs

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. If others near Boreham Street need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  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. Each joint is cut out and the edges inspected.
  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.

Getting the site ready

  • Have the specification and drawings to hand
  • Let us know about inductions and permits
  • Tell staff and tenants when we will be in

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Advice

For managing agents and facilities managers

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Boreham Street can sit alongside others in a wider programme.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Facades, frames and programmes in Boreham Street

Boreham Street sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager. The area within 2 miles of Boreham Street holds several hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.

Hospital estates such as Amberstone Hospital, 4 miles to the west of Boreham Street, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Boreham Street is about 5 miles north-west of Bexhill-on-Sea, in East Sussex. Looking for facade sealing in Boreham Street? We can help, as we do across East Sussex. Boreham Street is one of 308 places we cover in East Sussex for facade joints. Our Brighton page has more on work in that area.

Your questions answered

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

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Will you fit the mastic around our build programme in Boreham Street?

Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Should we check old sealant for asbestos?

For older buildings, yes, check before work starts. The dutyholder holds the asbestos register. Suspect material is left alone until it has been tested.

How many days will you need on site?

That varies with the scale of the job, though a typical visit typically takes a day or two for a few elevations, and longer where access has to be moved around the building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, let us know and we will send them with the quote.

What do you charge?

We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What we are called out for in Boreham Street

When sealant lets go of a frame or panel, the cause is often the preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly, and the joint opens with the first real movement.

Things that usually lead to an enquiry:

  • Patch repairs that keep failing
  • Perimeter sealant that has split or peeled away
  • Weathered joints at frame-to-structure perimeters
  • Hard, chalky sealant that no longer flexes

Hotels like White Friars Hotel (to the west of Boreham Street) rarely close for long, so refurbishment mastic is phased floor by floor.

What your quote should include

  • Who will actually carry out the work
  • Will failed sealant be removed rather than covered?
  • Is the sealant right for the movement and the substrate?
  • Health and safety accreditation such as CHAS
