Facade sealing in Hungerford Green, done properly

Managing agents and owners in Hungerford Green ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. If you have previous reseals run over old sealant and failed sealant on precast panel joints, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Hungerford Green, preparation and product choice get the time they need.

Sites around smaller places like Hungerford Green can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photographs and the programme and we’ll quote to suit.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

How the job changes by surface

Render and coated surfaces

Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.

Window and door perimeters

Frames grow and shrink with temperature, and the perimeter joint has to follow. The rod limits depth, leaving the bead able to flex without tearing.

When to call us in Hungerford Green

Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, so the new bead peels away within a season or two.

Things that normally lead to an enquiry:

  • Hard, chalky sealant that no longer flexes
  • Previous reseals run over old sealant
  • Leaks at window and door perimeters
  • Cladding panel joints that have opened up

Older buildings in the area around Hungerford Green, such as Basildon Park, 3.4 miles to the east of Hungerford Green, need care when sealed: the product has to suit soft or historic materials.

Before you book anyone

  • Will failed sealant be removed rather than covered?
  • Are they CHAS accredited or on Constructionline?
  • How long is the guarantee, and what does it include?
  • The named product and why it was chosen

Choosing a commercial sealant contractor

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 work around Hungerford Green, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Tell us what induction or permit system the site runs
  • Share the asbestos register for older buildings

Advice

Sites and facades in and around Hungerford Green

Rainfall across the South East, Hungerford Green included, is lower than in many parts of the UK. 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. Central London is about 47 miles from Hungerford Green. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.

For contractors at a school such as The Downs School, sealing has to be finished before term starts.

Building owners, agents and FMs in Hungerford Green

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Hungerford Green can sit alongside others in a wider programme across West Berkshire.

After the work

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Record the product and colour used on each elevation
  • Don’t wait for a second leak before calling
  • Share access with other external trades
  • Check that rainwater leaves the facade the way it was designed to

Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards.

Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading behind the facade.

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be 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.

Common questions from Hungerford Green clients

Is Hungerford Green off your patch?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

What documents will you need to give us for a job in Hungerford Green?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

How much does the work cost?

Every job gets its own fixed quote. For yours, speak to us on 01277 525 020 or email us.

Can you quote from photographs?

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

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Is it okay to overlay old mastic?

No. Overlaying is a shortcut that peels away quickly. We remove the failed sealant, clean the faces, set the depth and reseal.

Do you seal facades in winter?

Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things throughout the job.
