How we handle facade sealing in Broomfield

Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site, and we’ll fit the work around it. If you are dealing with weathered joints at frame-to-structure perimeters and discoloured or dirty facade joints, we can put it right. Facilities teams, main contractors and managing agents in Broomfield tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Building work in places the size of Broomfield is normally small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or email drawings and photos and we’ll come back to it.

Common problems we fix in Broomfield

Product choice matters: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Most external joints call for a neutral-cure, facade-grade sealant.

Clients usually get in touch after noticing one or more of the following:

  • Perimeter joints where frames meet the structure
  • Air leaks through failed facade joints
  • Damp patches beside frames after rain
  • Perimeter sealant that has split or peeled away

For contractors on a campus like Anglia Ruskin University, 2.1 miles south of Broomfield, facade and perimeter sealing has to fit around students and term dates.

What to look for in a quote

  • What level of public liability insurance do they hold?
  • How long is the guarantee, and what does it include?
  • Can the work be phased to keep areas open?
  • Do they follow the manufacturer’s priming guidance?

Our contractor checklist

Looking after the joints

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

  • Brief window cleaners about newly sealed joints
  • Plan facade sealing alongside redecoration
  • Keep sills, gutters and drainage paths clear
  • Confirm the survey covers external sealants in older buildings

Following storms, look inside for damp or staining near frames. An early report typically means a small reseal rather than a bigger repair.

Use each reseal to correct the joint: 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.

Our process

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For a site in Broomfield, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and the joint faces cleaned.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Warn occupants and staff about the work
  • Arrange parking or a loading space

For managing agents and facilities managers

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.

FAQs: Broomfield

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

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is a smaller place like Broomfield outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Can you look at water coming in around a frame?

Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout.

How much does the work cost?

There isn’t a price list, because every site is different. With photographs or drawings, we can give you a fixed quote.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

Will you quote for a small job?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Work on the window or framing system itself
  • Arranging specialist high-level access, which is planned with the client
  • Damaged frames that need replacing

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

What we seal

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

Why it’s worth doing now in Broomfield

The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Why us?

  • Clear, fixed quotes
  • Products installed to the manufacturer’s instructions
  • Joints cleaned back to sound surfaces
  • Constructionline member for supplier checks

Contractors’ notes for Broomfield

Broomfield 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 external mastic is timed for workable conditions and agreed with the site manager. At about 31 miles from central London, Broomfield is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.

When units on a site such as Regiment Business Park, 0.8 miles east of Broomfield, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. For a contractor at a hotel such as Channels Hotel (1.1 miles east of Broomfield), the mastic often has to be finished before a reopening date.

Broomfield is about 2 miles north of Chelmsford, in Essex. We cover commercial sites throughout Broomfield. Broomfield is one of 644 places in Essex on our list. There’s a separate page for London, about 31 miles away.
