What affects the price in Woodhatch

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Site requirements such as inductions and permits
  • Working within restricted access windows
  • Access and working height
  • Quantities, in metres or numbers

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

Details that help us quote

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • Asbestos survey details if the building is older
  • What the building is and how it’s used
  • Your programme or deadline
  • How the joints are reached, and at what height

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or send photos by email.

Facade sealing in Woodhatch, done properly

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on offices, blocks and industrial units. Where sealant is the specified fix, we also take on coping and flashing joints. If you are dealing with staining on stone next to old sealant and gaps between rainscreen or cladding panels, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Woodhatch is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Sites around smaller places like Woodhatch can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

What we are called out for in Woodhatch

Not every failure is in the sealant: if the edge of the render, concrete or coating breaks away, the bead goes with it. When the joint edges need repair first, we say so.

Any of the following is a good reason to get the joints checked over:

  • Gaps between rainscreen or cladding panels
  • Perimeter joints where frames meet the structure
  • Old perimeter mastic that has dried out
  • Facade joints cracked through the middle

Extensions at sites like Hollanden Park Hospital, 2.1 miles to the east of Woodhatch, typically sit beside working departments, and the mastic follows strict access rules.

Comparing quotes

  • Can the work be phased to keep areas open?
  • Which product they’ll use, and why it suits the joint
  • Whether old or failed sealant will be cut out, not overlaid
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

How to choose a sealant contractor

Maintenance after handover

A few simple habits keep the new joints working:

  • Don’t wait for a second leak before calling
  • Share access with other external trades
  • Check that rainwater leaves the facade the way it was designed to
  • Check the asbestos register before old mastic is disturbed

Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.

Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones behind the facade.

Sites and facades in and around Woodhatch

At about 23 miles from central London, Woodhatch is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. Woodhatch sits in one of the drier corners of the country, the South East. 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.

Older buildings in the area around Woodhatch, such as Knole House, 3 miles to the north of Woodhatch, need care when sealed: the product has to suit soft or historic materials. For contractors at a school such as Weald Community Primary School, sealing has to be finished before term starts.

When something else is needed

Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:

  • Cracked or spalling substrates that need repair before sealing
  • Water getting in through cracked render or porous masonry
  • Work on the window or framing system itself

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

What we seal

  • Perimeter joints where frames meet the structure
  • Shopfront frames
  • Coping and flashing joints
  • Stone and brick facade joints
  • Window and door perimeters
  • Cladding panel joints

Diagnose, treat, sign off

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Woodhatch, 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 start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and both faces cleaned back.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Have the specification and drawings to hand
  • Tell staff and tenants when we’ll be in
  • Send your site hours and access windows

Related advice

Woodhatch: questions and answers

Would you work within a site like Hollanden Park Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can work at a site such as University of Kent - Tonbridge fit around teaching?

Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Is it okay to overlay old mastic?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely. Nothing else gives a bond that lasts.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.

What type of sealant goes on window perimeters?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead, as the specification or substrate requires.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day.

Are you CHAS accredited and on Constructionline?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Work for main contractors and building owners

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
