Facade sealing in King's Somborne: the local picture

Central London is about 67 miles from King's Somborne. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand. Rainfall across the South East, King's Somborne included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.

Older buildings in the area around King's Somborne, such as Mottisfont Abbey (3.2 miles south-west of King's Somborne), need care when sealed: the product has to suit soft or historic materials. School extensions, at buildings such as King's Somborne Church of England Primary School, typically run to the summer holidays, mastic included.

King's Somborne is about 6 miles north of Romsey, in Hampshire. Commercial clients in King's Somborne can call on us for facade joints. 723 places across Hampshire fall within our area, King's Somborne among them. For work in that direction, see our Southampton page, about 12 miles away.

How we handle facade sealing in King's Somborne

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. If you are dealing with failed sealant on precast panel joints and damp patches beside frames after rain, we can help, whatever the surface. One point of contact handles commercial sealant work in King's Somborne from the first photographs to the final walk-round, whether it’s one building or several.

For a site near King's Somborne, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photographs and the programme let us give a fixed quote.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Questions about King's Somborne

Is a smaller place like King's Somborne outside your area?

No. Places such as King's Somborne are covered as much as the big towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

Can you work to our programme on a site in or near King's Somborne?

Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Will you check whether the sealant is causing the leak?

Yes. Photos are often enough to start, followed by a visit if needed. Many frame leaks are sealant failures, though not all, and we’ll be honest about which it is.

Do you provide access for facade work?

That comes down to the access arranged for the job. When you call 01277 525 020 or email a schedule or drawings, describe the access, and we will agree the approach together.

What will the job cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

Do you need to see the site first?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

Aftercare for building managers

Once the work is signed off, these steps help:

  • Combine resealing with other works that need access
  • Record the product and colour used on each elevation
  • Keep pressure washers away from fresh sealant
  • Check the asbestos register before old mastic is disturbed

Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and work stops until it’s tested if it’s suspected.

How the quote is worked out

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Access and working height
  • The site’s rules and procedures
  • Backing rod, priming and other preparation
  • Working within restricted access windows

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What to include in your enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Photos of the joints, close up and from further back
  • Where the site is, with the postcode
  • Any dates the work must fit around
  • The product your specification calls for

Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, give us a call on 01277 525 020 or email us.

Common problems we fix in King's Somborne

Product choice matters: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Neutral-cure, facade-grade products are what most external joints need.

Any of the following is a good reason to get the joints checked over:

  • Weathered joints at frame-to-structure perimeters
  • Facade joints cracked through the middle
  • Cold air coming in at window perimeters
  • Staining on stone next to old sealant

For a contractor working at a hospital such as Romsey Community Hospital, 5.8 miles south of King's Somborne, perimeter and facade sealing is planned around patients and deliveries.

Comparing quotes

  • Their plan for phasing and protecting the area
  • How long is the guarantee, and what does it include?
  • Whether old or failed sealant will be cut out, not overlaid
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Choosing a commercial sealant contractor

Diagnose, treat, sign off

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near King's Somborne need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

  • Send your site hours and access windows
  • Let us know about inductions and permits

Advice

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take 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.

Building owners, agents and FMs in King's Somborne

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
