Facade sealing in Rodmersham Green, done properly

Water ingress at window frames is a frequent reason facilities managers contact us. Very often the perimeter bead has cracked or lost its grip, though that isn’t the only cause. We will tell you if we think the leak is coming from somewhere sealant won’t fix. Most enquiries involve perimeter sealant that has split or peeled away and weathered facade joints that have lost their grip, across shopfront frames, window and door perimeters and perimeter joints where frames meet the structure. A specialist sealant contractor works differently from a general builder: on jobs in Rodmersham Green, preparation and product choice get the time they need.

Construction in and around smaller places such as Rodmersham Green is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

How a job runs

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking a day or two for a few elevations, and longer where access has to be moved around the building. Smaller jobs around Rodmersham Green can be grouped with others nearby. You will have a fixed quote before work starts.

  1. First we review photographs, 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.

Preparing the site

  • Warn occupants and staff about the work
  • Make sure the joints can be reached
  • Send your site hours and access windows

Maintenance after handover

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Investigate damp beside windows promptly
  • Record the product and colour used on each elevation
  • Check that rainwater leaves the facade the way it was designed to
  • Combine resealing with other works that need access

Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards using a matching sealant.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it.

General trades versus a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Questions we’re asked in Rodmersham Green

Will you plan work around the academic year at somewhere like Canterbury Christ Church University?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Do you take on work at healthcare sites like Sittingbourne Memorial Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

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, so we plan around the forecast.

Can you handle several sites?

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

Is any job too small?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Can you work while the building is occupied?

Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

Building owners, agents and FMs in Rodmersham Green

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Facades, frames and programmes in Rodmersham Green

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. Rodmersham Green has several hotels close by, all within 2 miles. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.

Building work at universities like Canterbury Christ Church University, 4.6 miles to the south-west of Rodmersham Green, is often timed for the summer, mastic included. Extensions at sites like Sittingbourne Memorial Hospital (to the north of Rodmersham Green) usually sit beside working departments, and the mastic follows strict access rules.

Quoting for work in Rodmersham Green

A fixed quote reflects the actual work. It allows for:

  • Backing rod, priming and other preparation
  • Phasing around occupants
  • Removal of failed or old sealant
  • Site requirements such as inductions and permits

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Sending details for a quote

Good information means a firmer quote. Helpful details to send:

  • Where the site is, with the postcode
  • Whether the building will be occupied during the work
  • Asbestos survey details if the building is older
  • The product your specification calls for

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

Common problems we fix in Rodmersham Green

Overlaying old sealant is a common shortcut that fails quickly. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.

Common reasons buildings call us in:

  • Damp patches beside frames after rain
  • Discoloured or dirty facade joints
  • Failed seals around shopfront and entrance frames
  • Cold air coming in at window perimeters

Projects at colleges like Sittingbourne College (1.6 miles north-west of Rodmersham Green) tend to run to term dates, so the mastic is planned tightly.
