Kitwood: questions and answers

Is Kitwood off your patch?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Does your area include sites such as Mansfield Business Park, near Kitwood?

Yes, sites like Mansfield Business Park are within our area, along with the rest of Kitwood. Photos and a short description are enough for a first look.

What will the job cost?

Every job gets its own fixed quote. For yours, call the office on 01277 525 020 or send photos by email with a description of the work.

How is access to upper-level joints handled?

That varies with the building and the access on offer. When you call 01277 525 020 or use the quote form, describe the access.

Can the building stay open while you work?

Typically, yes. We phase the work so most of the building stays in use, with each area protected and signed.

Do you seal facades in winter?

Year-round work is possible as long as joints are dry and temperatures suit the product. Frost and condensation on glass and steel are common on winter mornings.

Is old mastic on our building likely to contain asbestos?

It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder, and we will ask to see it. If asbestos is suspected, work stops until it is tested.

How we handle facade sealing in Kitwood

We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause. If the evidence points away from the sealant, we say so before quoting. The enquiries we see most involve sealant pulling away from frames or panels and unsightly perimeter sealant on a visible elevation, across coping and flashing joints, shopfront frames and perimeter joints where frames meet the structure. Looking for mastic applicators who cover Kitwood? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Construction in and around smaller places such as Kitwood 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.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

How a job runs

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For work around Kitwood, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  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. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Before we start on site

  • Move anything stored against the joints
  • Warn occupants and staff about the work
  • Point out parking and an unloading spot

Facades, frames and programmes in Kitwood

The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. At about 50 miles from central London, Kitwood is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.

Hospital estates such as Alton Community Hospital, 4.1 miles north-east of Kitwood, 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. Older buildings in the area around Kitwood, such as Bentworth Hall, which lies north of Kitwood, need care when sealed: the product has to suit soft or historic materials. When units on a site such as Mansfield Business Park, 1.4 miles to the north of Kitwood, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Kitwood is about 5 miles south-west of Alton, in Hampshire. Commercial clients in Kitwood use us for work on facade joints. Across Hampshire, 723 places are covered, including Kitwood. Our Southampton page has more on work in that area (19 miles or so).

Site staff or a sealant specialist?

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

How the job changes by surface

Cladding panel joints

On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end.

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building, so preparation and product choice matter.

Owners, agents and contractors

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

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

What happens if it’s left?

Topping up a failed joint normally buys very little time. A full cut-out and reseal costs more on the day but lasts much longer and avoids repeat call-outs. Converted and older buildings near places like Kitwood tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What you get with us

  • Work to your specification and the manufacturer’s guidance
  • Colour options checked against the specified product
  • CSCS-carded applicators
  • A fixed quote before work starts

Keeping the joints sound

For the best life from the joints:

  • Investigate damp beside windows promptly
  • Add perimeter sealant to planned maintenance checks
  • Plan facade sealing alongside redecoration
  • Insist on a full cut-out when joints are renewed

Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed.

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.
