About our facade sealing in Painters Ash

We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip, but not always. If the evidence points away from the sealant, we say so before quoting. We work on stone and brick facade joints, coping and flashing joints and perimeter joints where frames meet the structure, and the usual reasons a site gets in touch are damp patches beside frames after rain and draughts around frames and panels. Searching for sealant specialists in Painters Ash? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Building work in places the size of Painters Ash is usually small-scale: a handful of new houses, barn conversions, a school or hall extension. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

From enquiry to sign-off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. If neighbouring businesses or buildings around Painters Ash need work too, visits can be combined. Tell us your site hours and we’ll plan around them.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full.
  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.

Preparing the site

  • Move anything stored against the joints
  • Point out any areas we must not close
  • Tell staff and tenants when we’ll be in

How the job changes by surface

Cladding panel joints

On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end with backing and a facade-grade sealant.

Precast concrete panels

Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported before sealing.

Painters Ash: questions and answers

Can you work at a site such as Imperial Business Park, by Painters Ash?

Yes, sites like Imperial Business Park are within our area, along with the rest of Painters Ash. Photos and a short description are enough for a first look.

Is Painters Ash too small for you to travel to?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

What site paperwork can you supply?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Do we need an asbestos check before resealing?

In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first; if it’s suspected, work stops until it has been tested. Removal of asbestos isn’t something we do.

Can the sealant be colour-matched?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

Can you work on upper floors?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you are arranging and any site restrictions, and the quote will reflect it.

What we’re called out for in Painters Ash

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained and tears as the joint moves.

What tends to prompt an enquiry:

  • Air leaks through failed facade joints
  • Cladding panel joints that have opened up
  • Facade joints cracked through the middle
  • Weathered joints at frame-to-structure perimeters

For contractors refurbishing units at places like Imperial Business Park (1.6 miles north-east of Painters Ash), the mastic covers cladding panels, roller-door and window perimeters.

Comparing quotes

  • Whether old or failed sealant will be cut out, not overlaid
  • The terms of the workmanship guarantee
  • The named product and why it was chosen
  • How the joint faces will be prepared and primed

Choosing a commercial sealant contractor

What happens if it’s left?

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. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Why clients in Painters Ash choose us

  • Old sealant cut out, never sealed over
  • Colour options checked against the specified product
  • Fully insured, including public liability cover
  • Health and safety: CHAS accredited

See our cost guide or our accreditations and insurance.

Looking after the joints

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Confirm the survey covers external sealants in older buildings
  • Don’t wait for a second leak before calling
  • Note when each elevation was last resealed
  • Walk the elevations once or twice a year

Following storms, look inside for damp or staining near frames. An early report typically means a small reseal rather than a bigger repair.

Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down.
