Facade sealing in Colchester

External sealing depends on the weather more than most trades. 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 weathered joints at frame-to-structure perimeters and sealant pulling away from frames or panels, across coping and flashing joints, stone and brick facade joints and perimeter joints where frames meet the structure. A single leaking joint is often how a building in Colchester first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Bigger sites around a town like Colchester normally want mastic phased by plot, block or floor. Our CSCS-carded applicators follow the site induction and specification, and snags are closed before handover.

We stand by our work with a 12-month guarantee. That covers our preparation and application.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. 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. Sites in a big town such as Colchester frequently have reception sign-in, inductions and permits to work. Tell us about inductions, permits and site hours so the plan fits.

  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 both faces cleaned back.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Point out any areas we must not close
  • Flag any permit to work we will need
  • Move anything stored against the joints

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Related advice

Signs you need facade sealing in Colchester

When the sealant tears down its centre, it has normally been asked to move more than it can. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

Things that usually lead to an enquiry:

  • Weathered joints at frame-to-structure perimeters
  • Previous reseals run over old sealant
  • Unsightly perimeter sealant on a visible elevation
  • Perimeter sealant that has split or peeled away

Units on estates such as Colchester Retail Park, less than half a mile north-west of Colchester, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Before you book anyone

  • Can the work be phased to keep areas open?
  • Will RAMS and insurance details be available?
  • Are they CHAS accredited or on Constructionline?
  • What the guarantee covers, and for how long

Questions about Colchester

Is Colchester Retail Park, near Colchester, within your area?

Yes. Estates, retail parks and business parks around Colchester, Colchester Retail Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Would you work within a site like Oaks Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Can you fit around our working hours?

We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.

How is access to upper-level joints handled?

We agree access with the client at the start. Tell us about access: existing scaffold, what you’re arranging and any site restrictions, and we will price the work around it.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Should we check old sealant for asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Check the asbestos register or survey before it is disturbed; if it’s suspected, work stops until it has been tested. We don’t remove asbestos-containing materials.

Why deal with it now?

Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds. Businesses in Colchester often have several buildings with joints of a similar age. Renewing them in one programme saves time later.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

When something else is needed

Some faults sit outside our scope, and we say so rather than covering them up:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Joints too narrow for the movement they take, which need redesign
  • Render or concrete edges that have broken away

If in doubt, ring 01277 525 020 or use the quote form and we will say what we think.

Where we work in Colchester

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

Mastic packages on Colchester sites

At about 50 miles from central London, Colchester is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes. Plenty of hotels sit less than 2 miles from Colchester. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.

For a contractor working at a hospital such as Oaks Hospital, 1.1 miles north of Colchester, perimeter and facade sealing is planned around patients and deliveries. For contractors at a college like The Sixth Form College Colchester, less than half a mile north-west of Colchester, perimeters and internal sealant are timed for the holidays.

Colchester is in Essex. We cover commercial sites throughout Colchester. Our Essex coverage takes in 644 places, from busy centres to rural villages. Sites around London have their own page, roughly 50 miles from Colchester.

Business premises anywhere in CO4, CO3, CO2 and CO1 are within our area for facade joints. For a building on High Street, North Station Road and Durham Square or nearby, send details and we’ll quote for facade joints. You will find Colchester on or near the A12 and A120.

Further afield, our area takes in Braintree (14 miles west), Clacton-on-Sea (12 miles south-east), Maldon (15 miles south-west), Witham (13 miles south-west), Halstead (12 miles west) and Heybridge (14 miles south-west).

General trades versus a specialist

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, which is what makes a joint last.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
