Building and refurbishing in Marden Ash

Rainfall across the South East, Marden Ash included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. Marden Ash is about 20 miles from central London. 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.

For contractors refurbishing units at places like Hallsford Bridge Industrial Estate (0.7 miles east of Marden Ash), the mastic covers cladding panels, roller-door and window perimeters. Older buildings in the area around Marden Ash, such as Hill Hall, 4.2 miles to the west of Marden Ash, need care when sealed: the product has to suit soft or historic materials.

Marden Ash is about 6 miles north-west of Brentwood, in Essex. If you are looking for facade sealing in Marden Ash, we can help. Our Essex coverage takes in 644 places. For work in that direction, see our London page.

Facade sealing in Marden Ash, done properly

Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range, and cold, damp starts can delay work. We build that into the programme and tell you if the forecast changes the plan. If you are dealing with failed seals around shopfront and entrance frames and air leaks through failed facade joints, we can help, on stone and brick facade joints, cladding panel joints and window and door perimeters alike. Most enquiries from Marden Ash start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Around smaller places like Marden Ash, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Our workmanship is guaranteed for 12 months, in Marden Ash as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

FAQs: Marden Ash

Is a smaller place like Marden Ash outside your area?

Not at all. Marden Ash is within our area. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Can you work at a site such as Hallsford Bridge Industrial Estate, by Marden Ash?

Yes, sites like Hallsford Bridge Industrial Estate are within our area, along with the rest of Marden Ash. A few photographs and the unit address let us price the work.

Is it fine to apply new sealant on top of old?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

How much does the work cost?

Each job is quoted on its own details. To get one, give us a call on 01277 525 020 or email the details over.

Do you replace failed glazing units?

No. That work needs a glazing specialist. What we seal are the joints around frames and panels across the facade.

Can the sealant be colour-matched?

That depends on the product. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

Is it okay to overlay old mastic?

No. New sealant won’t hold on old sealant, so the old bead is cut away and the joint cleaned back to sound material. That is what makes the new joint last.

For managing agents and facilities managers

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

When to call us in Marden Ash

Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.

Most enquiries start with one or more of the following:

  • Facade joints cracked through the middle
  • Damp patches beside frames after rain
  • Cladding panel joints that have opened up
  • New sealant peeling off old mastic

Extensions at sites like St. Margaret's Hospital (to the west of Marden Ash) usually sit beside working departments, and the mastic follows strict access rules.

What your quote should include

  • Whether primer will be used where the manufacturer specifies it
  • Are they CHAS accredited or on Constructionline?
  • How long is the guarantee, and what does it include?
  • Whether old or failed sealant will be cut out, not overlaid

What sets the cost

Each job is priced on its own details. The main factors are:

  • Access and working height
  • How much there is to seal
  • Whether the work must be split into stages
  • Distance, for remote addresses

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

Before you send an enquiry

To price the job accurately, we need to understand the site. Send us:

  • Whether the building will be occupied during the work
  • Where the site is, with the postcode
  • A wide shot and a close-up of the area
  • Access details, including height

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, phone 01277 525 020 or use the quote form.

When to bring in a specialist

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

How a job runs

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Marden Ash can be grouped with others nearby. A fixed quote is given before anything starts.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Preparing the site

  • Send any specification or drawings in advance
  • Tell us your opening times and when work is allowed
  • Agree which areas must stay open

Why it’s worth doing now in Marden Ash

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Older rural buildings around Marden Ash move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Why appoint us

  • Over 20 years of commercial sealing
  • Colours confirmed for the specified product
  • One phone line for London, the South East and Scotland
  • 12 months’ guarantee on every job
