Facade sealing for Steventon End sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle facade sealing in Steventon End

We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip, but not always. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. If you’re dealing with perimeter joints where frames meet the structure and water coming in around window frames, we can help, whatever the surface. Most enquiries from Steventon End start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In the countryside around places like Steventon End, 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 comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email a schedule or drawings and we’ll come back to it.

Your questions answered

Do you cover business parks and estates near Steventon End, such as The Mount Business Park?

Yes. Our area takes in Steventon End and its surroundings, with estates and business parks such as The Mount Business Park included. To start, just call 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Is Steventon End off your patch?

No. Small places get the same service as large ones. 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.

Is old mastic on our building likely to contain asbestos?

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

Do you run new sealant over the existing bead?

No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.

How do we ask for a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or email drawings and photos. Include photographs or drawings if you have them.

How long will the new sealant last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Will you come and look before quoting?

It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

Why it’s worth doing now in Steventon End

Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, often turning up far from the joint. For buildings around smaller places like Steventon End, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Why appoint us

  • One number for every site we cover
  • Joints cleaned back to sound surfaces
  • Standard and matched colours in many product ranges
  • Commercial sealant work since 2005

Sites and facades in and around Steventon End

Rainfall across the South East, Steventon End included, is lower than in many parts of the UK. 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. Steventon End is about 43 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand.

When a school such as Ashdon Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Extensions at sites like Saffron Walden Community Hospital (3.9 miles south-west of Steventon End) usually sit beside working departments, and the mastic follows strict access rules.

Steventon End is about 4 miles north-east of Saffron Walden, in Essex. Any commercial site in Steventon End is covered. Across Essex, 644 places are covered, Steventon End among them. Our London page has more on work in that area (43 miles or so).

Signs you need facade sealing in Steventon End

The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Most external joints call for a neutral-cure, facade-grade sealant.

Things that usually lead to an enquiry:

  • New sealant peeling off old mastic
  • Hard, chalky sealant that no longer flexes
  • Discoloured or dirty facade joints
  • Facade joints cracked through the middle

New units and refits on sites such as The Mount Business Park, 2.7 miles north of Steventon End, need their panel and perimeter joints sealed to the specification.

Choosing a commercial sealant contractor

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Keep the sealant details on the building file
  • Ask about asbestos in pre-2000 mastic
  • Inspect facade joints on a regular cycle
  • Never let anyone seal over old sealant

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

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.

Cost factors for facade joints

The price varies from site to site. It mainly depends on:

  • How much there is to seal
  • The product specified
  • Location, for remote and island sites
  • Any access equipment needed

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Details that help us quote

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • The asbestos register, for older buildings
  • Drawings or a marked-up plan, if available
  • Anything awkward about access or site hours
  • Your programme or deadline

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

What the job involves on each surface

Window and door perimeters

Window and door perimeters make up most facade sealing work. A low-modulus, neutral-cure product suits most frame-to-wall joints, tooled to shed water.

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish, as the specification sets out.

On site: what to expect

Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. Rural sites near Steventon End 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. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and both faces cleaned back.
  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. We go over the completed work with you before leaving.

Before we start on site

  • Tell us which areas need to stay in use
  • Clear stock, furniture or equipment away from the joints
  • For older buildings, check the asbestos register before work

Ask for a quote

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
