Facade sealing in Shawford

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How a job runs

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. For work around Shawford, we aim to finish in one visit, so we ask for photos and rough sizes first. 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. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Before we start on site

  • Warn occupants and staff about the work
  • Tell us what induction or permit system the site runs
  • Have the specification and drawings to hand

Facade sealing in Shawford

External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range, and cold, damp starts can delay work. We plan for that and keep you updated. We work on coping and flashing joints, stone and brick facade joints and perimeter joints where frames meet the structure, and what we are called in for most is air leaks through failed facade joints and perimeter joints where frames meet the structure. Searching for sealant specialists in Shawford? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Construction in and around smaller places such as Shawford is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

A 12-month guarantee applies to all our work in Hampshire. Should something we installed fail, call the office on 01277 525 020 or email a schedule or drawings and we will come back to it.

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 where general trades tend to cut corners.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

What affects the price in Shawford

To price the job, we consider:

  • Travel to remote or island sites
  • Whether old sealant has to be cut out first
  • The site’s rules and procedures
  • Backing rod, priming and other preparation

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What we need to price the job

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

  • When you need the work done
  • Approximate linear metres or a joint schedule
  • Photos of the joints, close up and from further back
  • Access details, including height

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. For a chat about it beforehand, call the office on 01277 525 020 or use the quote form.

Facade sealing around Shawford: how the place shapes the job

Shawford is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team. Shawford lies roughly 63 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme.

Hospital estates such as Wessex Hospital (2.4 miles south-west of Shawford) 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. For contractors refurbishing units at places like Hazeley Enterprise Park, 0.9 miles east of Shawford, the mastic covers cladding panels, roller-door and window perimeters. When a school such as Compton All Saints Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Shawford is about 3 miles south of Winchester, in Hampshire. We send applicators to Shawford for facade joints, handled exactly as we handle every other area. Our Hampshire coverage takes in 723 places. For work in that direction, see our Southampton page (8 miles or so).

Commercial sites across SO21 are covered for facade joints. We cover commercial and managed buildings on Shawford Road and Pearson Lane and the roads nearby. Nearby places we also cover include Compton (1 mile west), Twyford (1 mile south-east), South Down (1 mile south-west), Otterbourne (1 mile south-west) and St Cross (2 miles north). Bigger towns within reach include Winchester (3 miles north), Eastleigh (4 miles south), Fareham (13 miles south-east), Andover (15 miles north-west), Totton (11 miles south-west) and Chandler's Ford (4 miles south-west).

Why it’s worth doing now in Shawford

Every shower drives water through a split perimeter bead. 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. One visit to deal with every failing joint makes more sense than several trips to a place like Shawford, rather than one at a time. Send photographs of each area and we will quote for the lot.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:

  • Render or concrete edges that have broken away
  • Providing access systems for the work
  • Work on the window or framing system itself

If you are not sure, just call 01277 525 020 or email us and we’ll give you a straight answer.

Where we work in Shawford

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

Different surfaces, different methods

Cladding panel joints

Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.

Perimeter joints at frames and structure

Perimeter joints at frames often show their age first. They are cut out, cleaned, backed and resealed using a sealant classified for that use.

Common questions from Shawford clients

Is Shawford too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Can you work on a hospital site such as Wessex Hospital?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

Can you find out why a window is leaking?

Yes. We check the sealant joints and report what we find. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

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.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
