Construction mastic for Woodcote Green sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Construction mastic for commercial buildings in Woodcote Green

We work to the specification and the programme rather than whatever product is to hand. If a product is named, that’s what goes in; any alternative we suggest is put to you before anything changes. Backing, primer and depth follow what the sealant maker sets out. We work on window and door perimeters, floor and skirting junctions and cladding and panel joints, and the failures we’re asked to look at most are old sealant on a refurbishment that needs stripping before new work and internal caulk splitting as the building dries out. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Woodcote Green, that means joint design, primers and backing rod as standard.

Every London site, Woodcote Green included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Alongside that, sites normally need booked deliveries and a plan for where materials go.

A 12-month guarantee applies to all our work in Greater London. Should something we installed fail, phone 01277 525 020 or send photos by email and we’ll come back to it.

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.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Your questions answered

Will you plan work around the academic year at somewhere like University for the Creative Arts - Epsom?

Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is Ullswater Industrial Estate, near Woodcote Green, within your area?

Yes. Estates, retail parks and business parks around Woodcote Green, Ullswater Industrial Estate among them, are all within reach. A few photos and the unit address let us price the work.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or use the quote form. Include photographs or drawings if you have them.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

What will the job cost?

Each job is quoted on its own details. To get one, call the office on 01277 525 020 or email us with a description of the work.

Is the mastic package guaranteed?

The work is guaranteed for 12 months. Keeping other trades off finished joints prevents most problems.

When something else is needed

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Faulty frames rather than failed sealant
  • Damage to finishes by other trades after we have sealed
  • Approving fire stopping as compliant

Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Joints and surfaces we work on

  • Window and door perimeters
  • Internal decorators’ caulk
  • Cladding and panel joints
  • Brick and block movement joints
  • Sanitary and kitchen joints
  • Floor and skirting junctions

What happens if it’s left?

Sealing over damaged or contaminated new joints might save a day. Sealant can’t grip a contaminated or existing bead, and the defect comes back after handover. We cut out and redo the joint properly. In Woodcote Green, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Why appoint us

  • Standard and matched colours in many product ranges
  • Fixed quotes based on photographs, drawings or a visit
  • RAL and finish matching where the product range allows
  • Commercial sealant work since 2005

See our cost guide or how we’re accredited.

Keeping the joints sound

To get the most from the new sealant:

  • Share drawings and the specification as soon as possible
  • Bring the mastic contractor in after the last trades are through
  • Keep finished joints away from paint, plaster and scrapers
  • Flag uneven or tapered frame gaps early

At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later. Tell us what records you need and we will confirm with the quote.

Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure. We raise them during our first walk of the area.

Cost factors for mastic packages

Quotes vary with the job. Expect it to depend on:

  • Site requirements such as inductions and permits
  • Any access equipment needed
  • Whether the work must be split into stages
  • Joint width, depth and condition

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.

Details that help us quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • How the joints are reached, and at what height
  • Your programme or deadline
  • Any specification or named product
  • Clear photos of the problem areas

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 will fill any gaps with a visit.

Mastic packages on Woodcote Green sites

There are several hotels within about 2 miles of Woodcote Green. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Site traffic in Woodcote Green falls within London’s ULEZ, like everywhere else in Greater London. Delivery slots and scarce storage shape how and when the mastic goes in.

New units and refits on sites such as Ullswater Industrial Estate, 1.7 miles to the south-east of Woodcote Green, need their panel and perimeter joints sealed to the specification. For a contractor working at a hospital such as Purley War Memorial Hospital, which lies east of Woodcote Green, perimeter and facade sealing is planned around patients and deliveries. For contractors at a school such as Wallington High School for Girls, sealing has to be finished before term starts.

Woodcote Green is about 1 mile west of Purley, in Greater London. We cover Woodcote Green, and jobs here get the same fixed quote and 12-month guarantee as anywhere else.

Our process

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. For a job in Woodcote Green, access comes first. Give us the hours we can be on site and we’ll schedule to suit.

  1. First we look at the scope on site or from drawings.
  2. A fixed quote sets out scope, products and phasing.
  3. Site paperwork is confirmed and our CSCS-carded applicators are inducted.
  4. We seal plot by plot or floor by floor in line with the programme.
  5. Problems we find, such as oversized gaps, are raised straight away.
  6. Final snagging is completed and the 12-month guarantee applies.

Preparing the site

  • Arrange parking or a loading space
  • Confirm the product named in the specification
  • Share your working hours and any access restrictions
