Contractors’ notes for Throwley Forstal

Throwley Forstal is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack. At about 44 miles from central London, Throwley Forstal is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes.

Historic houses such as Belmont House and Gardens, 1.1 miles north of Throwley Forstal, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. For contractors building in or near Throwley Forstal, we seal to the drawings, the specification and the programme.

Facade sealing for commercial buildings in Throwley Forstal

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. Site teams most often ask us about leaks at window and door perimeters and patch repairs that keep failing, on shopfront frames, perimeter joints where frames meet the structure and coping and flashing joints. For commercial sealant work in Throwley Forstal, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In the countryside around places like Throwley Forstal, 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 comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or email a schedule or drawings and we’ll come back to it.

From enquiry to sign-off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building around Throwley Forstal, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. We look at the joints, the drawings and the access before pricing.
  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. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Tell staff and tenants when we will be in
  • Share the asbestos register for older buildings
  • Make sure the joints can be reached

General trades versus a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

How the quote is worked out

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Whether old sealant has to be cut out first
  • Working within restricted access windows
  • Location, for remote and island sites
  • The size and state of each joint

The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

Before you send an enquiry

We can often quote from photos and a few details. It helps to include:

  • Approximate linear metres or a joint schedule
  • How the joints are reached, and at what height
  • Your programme or deadline
  • The product your specification calls for

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

Throwley Forstal: questions and answers

What site paperwork comes with a job in Throwley Forstal?

We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Can you keep pace with our programme in Throwley Forstal?

Yes. Send the programme and drawings, and we’ll 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.

What’s the quickest route to a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

Can you just add new sealant on top?

No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Can you fit around our working hours?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

Is Throwley Forstal in your area?

Yes. Sites across Throwley Forstal are covered.

Looking after the joints

Problems stay small when the joints are checked regularly. In particular:

  • Check the asbestos register before old mastic is disturbed
  • Walk the elevations once or twice a year
  • Combine resealing with other works that need access
  • Never let anyone seal over old sealant

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.

Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail.

Honest limits

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:

  • Joints too narrow for the movement they take, which need redesign
  • Specialist high-level access methods
  • Damp caused by condensation inside the building

Not sure which it is? You can call 01277 525 020 or email drawings and photos and we’ll tell you honestly.
