Facade sealing in Great Baddow

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

Why act early in Great Baddow

Scaffold or access already on site makes resealing much simpler. Combine it with planned external works and you only arrange access once, which is often the biggest saving. In a smaller place such as Great Baddow, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

What you get with us

  • Clear, fixed quotes
  • Work carried out by CSCS-carded applicators

Facade sealing for commercial buildings in Great Baddow

We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip. If the evidence points away from the sealant, we say so before quoting. Site teams most often ask us about new sealant peeling off old mastic and weathered facade joints that have lost their grip, on stone and brick facade joints, coping and flashing joints and cladding panel joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Great Baddow it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around places like Great Baddow, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

New build and refits around Great Baddow

Several hotels sit less than 2 miles from Great Baddow. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. Great Baddow is about 30 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.

On a campus such as Anglia Ruskin University, 2.2 miles to the north-west of Great Baddow, new teaching buildings and residences are usually built and refurbished around the academic year. For a contractor working at a hospital such as Phoenix Hospital (0.6 miles south of Great Baddow), perimeter and facade sealing is planned around patients and deliveries.

What we’re called out for in Great Baddow

New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead.

It’s worth sending us details if you spot any of the following:

  • Weathered facade joints that have lost their grip
  • Patch repairs that keep failing
  • Leaks at window and door perimeters
  • Staining on stone next to old sealant

Projects at schools like Baddow Hall Infant School work to term dates, so mastic is programmed tightly.

Questions to ask before you book

  • How joint depth will be controlled
  • Can the work be phased to keep areas open?
  • How the existing material will be dealt with
  • Their pre-qualification and accreditations

Questions to ask before you appoint anyone

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Redoing a failed joint normally 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.

Maintenance after handover

Once the work is signed off, a little attention goes a long way:

  • Keep sills, gutters and drainage paths clear
  • Avoid harsh cleaners on facade sealant
  • Investigate damp beside windows promptly
  • Insist on a full cut-out when joints are renewed

Look at perimeter and panel joints as part of routine building checks. Watch for splits, gaps at the edges, hardening and discolouration.

Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.

What the job involves on each surface

Window and door perimeters

Frame materials vary, and so does the preparation. We clean and prime to the sealant maker’s guidance for each surface.

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint, not the framing or glazing itself.

Questions we’re asked in Great Baddow

Is Great Baddow too far out for you?

Not at all. Great Baddow is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can work at a site such as Anglia Ruskin University fit around teaching?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

How many days will you need on site?

It depends on the scope, though a typical visit normally takes a day or two for a few elevations, and longer where access has to be moved around the building. For bigger or phased jobs, we’ll set out a timescale with the quote.

Will you check whether the sealant is causing the leak?

Yes. We check the sealant joints and report what we find. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

What site paperwork can you supply?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

From enquiry to sign-off

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself normally taking a day or two for a few elevations, and longer where access has to be moved around the building. Several jobs near Great Baddow can be grouped on one trip. Tell us your site hours and we’ll plan around them.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out 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. The finished joints are checked with you.

Preparing the site

  • Warn occupants and staff about the work
  • Share the asbestos register for older buildings
  • Clear stock, furniture or equipment away from the joints
