About our facade sealing in Molehill Green

We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds. If you have old perimeter mastic that has dried out and damp patches beside frames after rain, we can put it right. One point of contact handles commercial sealant work in Molehill Green from the first photos to the final walk-round, for single jobs and planned programmes alike.

Construction in and around smaller places such as Molehill Green is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Questions we’re asked in Molehill Green

Is a hospital such as Herts and Essex Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Does your area include sites such as Mill End Business Centre, near Molehill Green?

Yes. Our area takes in Molehill Green and its surroundings, with estates and business parks such as Mill End Business Centre included. Send details of the unit and the work through our quote form for a quick quote.

How many days will you need on site?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.

Do we need an asbestos check before resealing?

It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder. Suspect material is left alone until it has been tested.

Do you guarantee your work?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Should maintenance staff do it?

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 typically costs more in the end than doing them right.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Keeping the joints sound

Once the work is signed off, these steps help:

  • Avoid harsh cleaners on facade sealant
  • Keep the sealant details on the building file
  • Keep sills, gutters and drainage paths clear
  • Plan facade sealing alongside redecoration

Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead.

Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.

Different surfaces, different methods

Brick and stone facades

Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one.

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface.

On site: what to expect

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building around Molehill Green, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed 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. We go over the completed work with you before leaving.

What we need from you

  • Warn occupants and staff about the work
  • Flag any permit to work we will need
  • For older buildings, check the asbestos register before work

Request a quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or email drawings and photos.

Facade sealing in Molehill Green: the local picture

Molehill Green is about 32 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes. The area within 2 miles of Molehill Green holds several hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.

Older buildings in the area around Molehill Green, such as Horham Hall (3.2 miles north-east of Molehill Green), need care when sealed: the product has to suit soft or historic materials. New wings at hospitals like Herts and Essex Hospital, 4.9 miles to the south-west of Molehill Green, bring long runs of window and panel joints to seal.

When to call us in Molehill Green

When the sealant tears down its centre, it has usually been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

If one of these sounds familiar, it’s time for a closer look:

  • Water coming in around window frames
  • Gaps between rainscreen or cladding panels
  • Sealant pulling away from frames or panels
  • Patch repairs that keep failing

Projects at colleges like Arthur Findlay College, 2.7 miles west of Molehill Green, tend to run to term dates, so the mastic is planned tightly.

Questions to ask before you book

  • Their approach to joint depth and backing
  • Their pre-qualification and accreditations
  • Will RAMS and insurance details be available?
  • The terms of the workmanship guarantee
