Facade sealing in Steep

About our facade sealing in Steep

Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. The enquiries we see most involve failed seals around shopfront and entrance frames and gaps between rainscreen or cladding panels, on perimeter joints where frames meet the structure, shopfront frames and cladding panel joints. A specialist sealant contractor works differently from a general builder: on jobs in Steep, preparation and product choice get the time they need.

For a site near Steep, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photos and the programme and we’ll quote to suit.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Commercial clients in Steep

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

How the quote is worked out

Each job is priced on its own details. The main factors are:

  • Distance, for remote addresses
  • Backing rod, priming and other preparation
  • Whether old sealant has to be cut out first
  • Quantities, in metres or numbers

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What we need to price the job

We can often quote from photos and a few details. Please tell us:

  • Approximate linear metres or a joint schedule
  • The site address and postcode
  • A wide shot and a close-up of the area
  • The product your specification calls for

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or phone 01277 525 020 or email us to discuss it first.

Why it’s worth doing now in Steep

The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Early action keeps it simple. For buildings around smaller places like Steep, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

What you get with us

  • One contact handling all your sites
  • Our applicators hold CSCS cards
  • Joints cleaned back to sound surfaces
  • Fully insured, including public liability cover

Building and refurbishing in Steep

Steep sits in one of the drier corners of the country, the South East. 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 49 miles from Steep. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.

New wings at hospitals like Petersfield Hospital (to the south of Steep) bring long runs of window and panel joints to seal. Recladding or extending a unit at a site like Upper Adhurst Industrial Park, 1.8 miles to the east of Steep, brings panel joints and frame perimeters into the programme. Projects at schools like Steep Church of England Voluntary Controlled Primary School work to term dates, so mastic is programmed tightly.

Steep is about 1 mile north of Petersfield, in Hampshire. Commercial clients in Steep use us for work on facade joints, as part of our coverage of Hampshire. Steep is one of 723 places we cover in Hampshire for facade joints. We also cover Portsmouth, around 16 miles from Steep.

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Redoing a failed joint typically 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.

Diagnose, treat, sign off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. If others near Steep need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  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. 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.

Getting the site ready

  • Send any specification or drawings in advance
  • Clear stock, furniture or equipment away from the joints
  • Let building users know which areas are affected

Request a quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

FAQs: Steep

Can you work at a site such as Upper Adhurst Industrial Park, by Steep?

Yes. We cover Steep and the area around it, including industrial estates, business parks and retail parks such as Upper Adhurst Industrial Park. Send details of the unit and the work through our quote form for a quick quote.

Would you work within a site like Petersfield Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

Will you quote for a small job?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

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.

Is it okay to overlay old mastic?

No. Overlaying is a shortcut that peels away quickly. Our method is a full cut-out, cleaning, backing and a new bead.
