Facade sealing for Duton Hill sites

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

How we handle facade sealing in Duton Hill

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, and closed-cell rod sets the depth, keeping the bond to two faces, often at around 2:1 width to depth, as the manufacturer advises. Site teams most often ask us about new sealant peeling off old mastic and weathered joints at frame-to-structure perimeters, on shopfront frames, coping and flashing joints and cladding panel joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Duton Hill, preparation and product choice get the time they need.

In the countryside around places like Duton Hill, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When to call us in Duton Hill

Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, then it splits or peels.

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

  • Water coming in around window frames
  • New sealant peeling off old mastic
  • Old perimeter mastic that has dried out
  • Discoloured or dirty facade joints

Units on estates such as Williams Field Business Centre (to the west of Duton Hill) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Before you book anyone

  • Are they CHAS accredited or on Constructionline?
  • How the joint faces will be prepared and primed
  • What the guarantee covers, and for how long
  • How they’ll work around occupants

Choosing a commercial sealant contractor

Cost factors for facade joints

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • How much existing material needs removing
  • The site’s rules and procedures
  • Which sealant the job calls for
  • Phasing around occupants

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 fixed quote once you have the details.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • When you need the work done
  • Anything awkward about access or site hours
  • Asbestos survey details if the building is older
  • The type of building and who uses it

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

From enquiry to sign-off

Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. If others near Duton Hill need work, visits can be combined. You will have a fixed quote before work starts.

  1. Photos, drawings or a visit tell us about the joints and the 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.

What we need from you

  • Explain the parking and delivery arrangements
  • Clear stock, furniture or equipment away from the joints
  • Let us know about inductions and permits

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Duton Hill: questions and answers

Is Duton Hill too small for you to travel to?

No. Places such as Duton Hill are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you work at a site such as Williams Field Business Centre, by Duton Hill?

Yes. We cover Duton Hill and the area around it, including industrial estates, business parks and retail parks such as Williams Field Business Centre. A few photos and the unit address let us price the work.

What will the job cost?

It depends on the job: quantities, access, the product and any phasing. Call for a quote.

How many days will you need on site?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

Do you take on multi-site work?

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

Will rain stop the work?

We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Cold, damp mornings can delay a start.

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.

Maintenance after handover

To get the most from the new sealant:

  • Keep pressure washers away from fresh sealant
  • Walk the elevations once or twice a year
  • Keep the sealant details on the building file
  • Clear debris that holds water against joints

Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant.

Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money.

Contractors’ notes for Duton Hill

Duton Hill is about 34 miles from central London. 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. Duton Hill 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 the external programme keeps a little slack.

Older buildings in the area around Duton Hill, such as Horham Hall, 1.9 miles to the north-west of Duton Hill, need care when sealed: the product has to suit soft or historic materials. Projects at schools like Putteridge High School work to term dates, so mastic is programmed tightly.

Duton Hill is about 8 miles north-east of Bishop's Stortford, in Essex. Commercial clients in Duton Hill use us for work on facade joints. We work across 644 places in Essex, from busy centres to rural villages. There’s a separate page for London, about 34 miles away.

Surface by surface

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. We avoid acetoxy silicone, which can stain some natural stone.

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building.

General trades versus a specialist

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
