Facade sealing for Stonymarsh sites

Facade sealing in Stonymarsh

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. Most enquiries involve damp patches beside frames after rain and perimeter sealant that has split or peeled away, across cladding panel joints, perimeter joints where frames meet the structure and stone and brick facade joints. Most enquiries from Stonymarsh start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

In the countryside around places like Stonymarsh, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.

Work we carry out in Hampshire comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or email us and we will arrange a return visit.

Work for main contractors and building owners

CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Building owners and managing agents use us on everything from one building to a spread of sites around Stonymarsh. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Why deal with it now?

Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. Converted and older buildings near places like Stonymarsh tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Why clients in Stonymarsh choose us

  • Matching to RAL references, product permitting
  • One contact handling all your sites
  • Workmanship guaranteed for 12 months
  • Old sealant cut out, never sealed over

Questions we are asked in Stonymarsh

Will you take on work at estates like Yokesford Hill Industrial Estate, close to Stonymarsh?

Yes. We cover Stonymarsh and the area around it, including industrial estates, business parks and retail parks such as Yokesford Hill Industrial Estate. A few photos and the unit address let us price the work.

Can you take on a job at a hospital such as Romsey Community Hospital?

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.

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Can the sealant be colour-matched?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

What do you charge?

We don’t publish prices, because every site is different. Send photos or drawings and we will price it at a fixed figure.

Do you provide access for facade work?

We agree access with the client at the start. Tell us about access: existing scaffold, what you’re arranging and any site restrictions.

What sets the cost

A fixed quote reflects the actual work. It takes account of:

  • Joint width, depth and condition
  • Any access equipment needed
  • How much there is to seal
  • Removal of failed or old sealant

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Sending details for a quote

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

  • Photos of the joints, close up and from further back
  • Whether an asbestos survey exists
  • What the building is and how it’s used
  • Approximate linear metres or a joint schedule

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or email drawings and photos.

From enquiry to sign-off

Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Rural sites near Stonymarsh may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We start with photographs, drawings or a visit to see the joints and agree 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. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Preparing the site

  • Agree which areas must stay open
  • Let us know about inductions and permits
  • Tell staff and tenants when we will be in

Ask for a quote

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Related advice

Aftercare for building managers

Problems stay small when the joints are checked regularly. Specifically:

  • Add perimeter sealant to planned maintenance checks
  • Share access with other external trades
  • Don’t wait for a second leak before calling
  • Keep the sealant details on the building file

Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade.

Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down.

Mastic packages on Stonymarsh sites

Stonymarsh is about 69 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. Stonymarsh sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.

With historic properties like Mottisfont Abbey, 0.5 miles west of Stonymarsh, in the area, refurbishment work often meets old masonry that needs compatible sealants. For a contractor working at a hospital such as Romsey Community Hospital, 3.7 miles to the south-east of Stonymarsh, perimeter and facade sealing is planned around patients and deliveries. Recladding or extending a unit at a site like Yokesford Hill Industrial Estate (2.2 miles south-east of Stonymarsh) brings panel joints and frame perimeters into the programme.

Stonymarsh is about 4 miles north-west of Romsey, in Hampshire. Our applicators travel to Stonymarsh for work on facade joints, handled exactly as we handle every other area. 723 places across Hampshire fall within our area, including Stonymarsh. We also cover Southampton, some 10 miles away.

Site staff or a sealant specialist?

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Putting right a botched joint often costs more than sealing it well at the start, 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.
