Facade sealing for commercial buildings in Whitehill

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits. We build that into the programme and tell you if the forecast changes the plan. We work on shopfront frames, coping and flashing joints and window and door perimeters, and the usual reasons a site gets in touch are perimeter sealant that has split or peeled away and unsightly perimeter sealant on a visible elevation. One point of contact handles commercial sealant work in Whitehill from the first photos to the final walk-round, for single jobs and planned programmes alike.

Conversions around smaller places like Whitehill often join new frames to old masonry or timber, which leaves joints between old walls and new frames that need a sealant able to take the movement.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Leave it or put it right?

Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Leaks travel along the structure. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you are ready.

Why appoint us

  • Sealing commercial buildings since 2005
  • A fixed quote before work starts
  • One contact handling all your sites
  • Standard and matched colours in many product ranges

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Your questions answered

Will you take on work at estates like Woolmer Trading Estate, close to Whitehill?

Yes. Estates, retail parks and business parks around Whitehill, Woolmer Trading Estate among them, are all within reach. Photos and a short description are enough for a first look.

Is Whitehill too small for you to travel to?

Not at all. Whitehill is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

What do you charge?

It depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.

Are you insured?

Yes. We are fully insured, including public liability cover.

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How do we ask for a quote?

The quote form is the simplest route, though you can also call the office on 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Cost factors for facade joints

A fixed quote reflects the actual work. It allows for:

  • Any access equipment needed
  • The total length or number of joints
  • Backing rod, priming and other preparation
  • How much existing material needs removing

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Before you send an enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • The type of building and who uses it
  • The asbestos register, for older buildings
  • Rough lengths or quantities, or drawings if you have them
  • Any specification or named product

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, phone 01277 525 020 or email the details over.

Building and refurbishing in Whitehill

Whitehill lies roughly 43 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.

Projects at schools like Woodlea Primary School work to term dates, so mastic is programmed tightly. Hospital estates such as Chase Hospital, under half a mile to the north-east of Whitehill, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Whitehill is about 6 miles south-east of Alton, in Hampshire. If you are looking for facade sealing in Whitehill, we can help, as we do across Hampshire. 723 places across Hampshire fall within our area, including Whitehill.

When to call us in Whitehill

New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.

Common reasons buildings call us in:

  • Facade joints cracked through the middle
  • Previous reseals run over old sealant
  • Hard, chalky sealant that no longer flexes
  • Leaks at window and door perimeters

When units on a site such as Woolmer Trading Estate (under half a mile north of Whitehill) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Questions to ask before you appoint anyone

On site: what to expect

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Work in places the size of Whitehill is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.

  1. We start with photographs, drawings or a visit to see the joints and agree 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.

Preparing the site

  • Share the asbestos register for older buildings
  • Confirm the product named in the specification
  • Point out any areas we must not close
