Why it’s worth doing now in Goddard's Green

Every shower drives water through a split perimeter bead. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing now costs less than repairing interiors later. Around Goddard's Green, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.

Pricing facade joints depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.

Why us?

  • Failed material removed, not covered up
  • RAL and finish matching where the product range allows
  • Fully insured, including public liability cover
  • Commercial sealant work since 2005

Facade sealing in Goddard's Green, done properly

We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure. Coping and flashing joints are included where sealant is the specified fix. The enquiries we see most involve staining on stone next to old sealant and sealant pulling away from frames or panels, on coping and flashing joints, window and door perimeters and shopfront frames. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Goddard's Green it comes down to the same thing: the right product in a properly prepared joint.

Construction in and around smaller places such as Goddard's 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.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or email a schedule or drawings and we’ll arrange a return visit.

What sets the cost

We price every job individually. The things that drive the figure:

  • Phasing around occupants
  • Whether old sealant has to be cut out first
  • Backing rod, priming and other preparation
  • Travel to remote or island sites

The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.

What we need to price the job

Whether it’s one area or a whole building, these details speed things up:

  • Clear photographs of the problem areas
  • What the building is and how it’s used
  • Any dates the work must fit around
  • How the joints are reached, and at what height

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Sites and facades in and around Goddard's Green

At about 42 miles from central London, Goddard's Green is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. Goddard's Green sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.

Units on estates such as Theale Lakes Business Park (to the north-west of Goddard's Green) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Older buildings in the area around Goddard's Green, such as Stratfield Saye House (3.7 miles south-east of Goddard's Green), need care when sealed: the product has to suit soft or historic materials. When a school such as Garland Junior School is extended or refurbished, the mastic package is often squeezed into the holidays.

Goddard's Green is about 5 miles south-west of Reading, in West Berkshire. We send applicators to Goddard's Green for facade joints. Our West Berkshire coverage takes in 140 places, from busy centres to rural villages.

General trades versus a specialist

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. Getting these wrong usually costs more in the end than doing them right.

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.

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

How a job runs

Diagnose, treat, 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 Goddard's Green, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We look at the joints, the drawings and the access before pricing.
  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

  • Share the asbestos register for older buildings
  • Send your site hours and access windows
  • Tell staff and tenants when we’ll be in

Advice

What sealant work can’t fix

  • Specialist high-level access methods
  • Replacing glass or failed glazing units

If in doubt, call 01277 525 020 or email the details over and we’ll say what we think.

Your questions answered

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

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Goddard's Green too small for you to travel to?

No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, which many sites require.

Are you insured?

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

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

What will the job cost?

That depends on the job: quantities, access, the product and any phasing. Call for a quote.
