Facade sealing for businesses in Hyde

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

Different surfaces, different methods

Brick and stone facades

Joints in natural stone need care to avoid staining. The specified stone-compatible sealant is what we use.

Perimeter joints at frames and structure

Perimeter joints at frames often show their age first. They are cut out, cleaned, backed and resealed using a sealant classified for that use.

Facade sealing for commercial buildings in Hyde

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on offices, blocks and industrial units. Coping and flashing joints are included where sealant is the specified fix. We work on perimeter joints where frames meet the structure, stone and brick facade joints and cladding panel joints, and the failures we’re asked to look at most are cladding panel joints that have opened up and draughts around frames and panels. Facilities teams, main contractors and managing agents in Hyde tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

For a contractor on a smaller site near Hyde, one mastic visit at the right stage saves return trips. Let us know the key stages and we’ll time the work so nothing waits on us.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. For a site in Hyde, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Have the specification and drawings to hand
  • Tell us your opening times and when work is allowed

Why act early in Hyde

The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

What you get with us

  • Over 20 years of commercial sealing
  • Work to your specification and the manufacturer’s guidance
  • One phone line for London, the South East and Scotland
  • Colours chosen to suit frames, cladding or finishes where possible

Commercial clients in Hyde

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

How the quote is worked out

Each job is priced on its own details. The things that drive the figure:

  • Location, for remote and island sites
  • Whether the work must be split into stages
  • Site requirements such as inductions and permits
  • How accessible the joints are

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Before you send an enquiry

Good information means a firmer quote. Helpful details to send:

  • Specification clauses that apply
  • Asbestos survey details if the building is older
  • When you need the work done
  • Where the site is, with the postcode

For a fixed quote, speak to us on 01277 525 020 or use the quote form, telling us the site location and the nature of the job. You can also send details through our quote form.

Hyde: questions and answers

Is Hyde too far out for you?

Not at all. Hyde is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Is hospital work, at somewhere like Royal Hampshire County Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

How long does a job like this take?

It depends on the scope, though a typical visit usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For bigger or phased jobs, we will set out a timescale with the quote.

Do you replace failed glazing units?

No. We don’t install glazing systems, windows or glass. We seal the joints around them, such as perimeter joints where frames meet the structure.

Do you use silicone for external joints?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, as the specification or substrate requires.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

When can you be on site?

Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.

Sites and facades in and around Hyde

Plenty of hotels sit less than 2 miles from Hyde. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight. Hyde is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager.

Hotels like The Winchester Hotel and Spa (to the west of Hyde) rarely close for long, so refurbishment mastic is phased floor by floor. On a campus such as University of Winchester, 0.9 miles south-west of Hyde, new teaching buildings and residences are usually built and refurbished around the academic year. For contractors at a college like Peter Symonds College (0.5 miles west of Hyde), perimeters and internal sealant are timed for the holidays.

Hyde is about 1 mile north of Winchester, in Hampshire. Any commercial site in Hyde is covered, whether it’s a single job or part of a planned programme. We work across 723 places in Hampshire, large and small. Southampton is covered too, some 11 miles away.

If you need facade sealing in SO23, SO22 and SO20, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. For a building on Elm Road, Swan Lane and City Road or nearby, send details and we’ll quote for facade joints. Close to Hyde, our area also takes in Abbotts Barton (1 mile north-east), Winchester (1 mile south), Weeke (1 mile west), Highcliffe (1 mile south-east) and Bar End (1 mile south). Further afield, our area takes in Eastleigh (7 miles south), Andover (12 miles north-west), Totton (13 miles south-west), Chandler's Ford (7 miles south-west), Hedge End (11 miles south) and Romsey (9 miles south-west).
