Questions we’re asked in Knave's Ash

Will you take on work at estates like Chislet Business Park, close to Knave's Ash?

Yes, sites like Chislet Business Park are within our area, along with the rest of Knave's Ash. Send details of the unit and the work through our quote form for a quick quote.

Could you schedule work at a campus like University of Kent for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Do you cover Knave's Ash?

Yes. We cover Knave's Ash, and you can speak to us on 01277 525 020 or email drawings and photos to get started.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Facade sealing in Knave's Ash

We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds. We work on stone and brick facade joints, cladding panel joints and window and door perimeters, and the failures we’re asked to look at most are hard, chalky sealant that no longer flexes and leaks at window and door perimeters. One point of contact handles commercial sealant work in Knave's Ash from the first photos to the final walk-round, for single jobs and planned programmes alike.

Construction in and around smaller places such as Knave's Ash 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.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

General trades versus a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

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.

Why act early in Knave's Ash

If access is already up for other work, resealing at the same time makes sense. Combine it with planned external works and you only arrange access once, which is often the biggest saving. Around Knave's Ash, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

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.

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather.

Cladding panel joints

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

Signs you need facade sealing in Knave's Ash

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.

Things that typically lead to an enquiry:

  • Sealant pulling away from frames or panels
  • Failed sealant on precast panel joints
  • Draughts around frames and panels
  • Water coming in around window frames

Hospital estates such as Queen Victoria Memorial Hospital, 2.4 miles to the north of Knave's Ash, 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.

What to look for in a quote

  • What the guarantee covers, and for how long
  • Will RAMS and insurance details be available?
  • Is the sealant right for the movement and the substrate?
  • How joint depth will be controlled

Our contractor checklist

From enquiry to sign-off

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around Knave's Ash can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  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. We walk the finished joints with you before handing over.

What we need from you

  • Flag any permit to work we’ll need
  • Agree which areas must stay open
  • For older buildings, check the asbestos register before work
