Facade sealing around Sheet: points for this area

Sheet sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. Central London is about 49 miles from Sheet. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

For a contractor working at a hospital such as Petersfield Hospital, 1.3 miles south-west of Sheet, perimeter and facade sealing is planned around patients and deliveries. Work at a hotel such as The Red Lion Hotel (1 mile south-west of Sheet) tends to be programmed around bookings, mastic included. Historic houses such as Uppark (to the south of Sheet) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Sheet is about 1 mile north-east of Petersfield, in Hampshire. Looking for facade sealing in Sheet? We can help, as we do across Hampshire. We work across 723 places in Hampshire. Our Portsmouth page has more on work in that area, about 16 miles away.

Nearby places we also cover include Petersfield (1 mile south-west), Steep (1 mile north-west), Steep Marsh (1 mile north-west), Stroud (2 miles west) and Oakshott (2 miles north-west) for facade joints.

Facade sealing for commercial buildings in Sheet

Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits. We plan for that and keep you updated. If you’re dealing with discoloured or dirty facade joints and previous reseals run over old sealant, we can help, whatever the surface. One point of contact handles commercial sealant work in Sheet from the first photos to the final walk-round, whether it’s one building or several.

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

A 12-month guarantee applies to all our work in Hampshire. Should something we installed fail, phone 01277 525 020 or email a schedule or drawings and we’ll come back to it.

What we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Water getting in through cracked render or porous masonry
  • Cracked or spalling substrates that need repair before sealing
  • Movement beyond what any sealant can handle

If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think before you book.

Where we work in Sheet

  • Window and door perimeters
  • Coping and flashing joints
  • Stone and brick facade joints
  • Perimeter joints where frames meet the structure
  • Shopfront frames
  • Cladding panel joints

Keeping the joints sound

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Keep pressure washers away from fresh sealant
  • Insist on a full cut-out when joints are renewed
  • Confirm the survey covers external sealants in older buildings
  • Add perimeter sealant to planned maintenance checks

Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.

Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.

For managing agents and facilities managers

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

What happens if it’s left?

Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. Older rural buildings around Sheet move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

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

How the quote is worked out

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

  • The size and state of each joint
  • Induction, permit and paperwork requirements
  • Travel to remote or island sites
  • Working within restricted access windows

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.

Sending details for a quote

A few photographs plus some basic facts will normally do. Please tell us:

  • Anything awkward about access or site hours
  • Drawings or a marked-up plan, if available
  • Any dates the work must fit around
  • Where the site is, with the postcode

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Sheet: questions and answers

Is Sheet too small for you to travel to?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Would you work within a site like Petersfield Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

How long does a job like this take?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.

Will you check whether the sealant is causing the leak?

Yes. We check the sealant joints and report what we find before quoting. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.

Is colour matching possible?

It depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

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 use the quote form. Photos, drawings or a joint schedule help us quote quickly.

Our process

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 handed back before the next one starts. Jobs in and around smaller places like Sheet are typically planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Preparing the site

  • Confirm the product named in the specification
  • Warn occupants and staff about the work
  • Share your working hours and any access restrictions
