Facade sealing for Newney Green sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Facade sealing in Newney Green, done properly

We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause. We will tell you if we think the leak is coming from somewhere sealant won’t fix. If you are dealing with gaps between rainscreen or cladding panels and leaks at window and door perimeters, we can help, whatever the surface. Whoever orders the work in Newney Green, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Conversions of older rural buildings near smaller places such as Newney Green bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Mastic packages on Newney Green sites

At about 26 miles from central London, Newney Green is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager.

Building work at universities like Writtle University College Cow Watering Campus (0.7 miles east of Newney Green) is often timed for the summer, mastic included. Historic houses such as Hylands, 2.7 miles to the south-east of Newney Green, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Newney Green is about 4 miles west of Chelmsford, in Essex. Businesses, contractors and managing agents in Newney Green can call on us for facade joints. Newney Green is one of 644 places we cover in Essex for facade joints. London is covered too, around 26 miles from Newney Green.

What sealant work can’t fix

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Work on the window or framing system itself
  • Damp caused by condensation inside the building
  • Joints whose design needs changing by the specifier

If in doubt, call the office on 01277 525 020 or email drawings and photos and we’ll say what we think.

Joints and surfaces we work on

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

Maintenance after handover

Regular inspection catches problems early. Specifically:

  • Ask about asbestos in pre-2000 mastic
  • Clear debris that holds water against joints
  • Investigate damp beside windows promptly
  • Never let anyone seal over old sealant

Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.

Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Quoting for work in Newney Green

We price every job individually. The main factors are:

  • Quantities, in metres or numbers
  • Access and working height
  • Site requirements such as inductions and permits
  • Which sealant the job calls for

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What to include in your enquiry

However big the job, these details speed things up:

  • Photos of the joints, close up and from further back
  • How the joints are reached, and at what height
  • Rough lengths or quantities, or drawings if you have them
  • The type of building and who uses it

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to call the office on 01277 525 020 or email the details over.

Building owners, agents and FMs in Newney Green

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.

What we’re called out for in Newney Green

New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.

Clients usually get in touch after noticing something like this:

  • New sealant peeling off old mastic
  • Perimeter sealant that has split or peeled away
  • Perimeter joints where frames meet the structure
  • Old perimeter mastic that has dried out

School extensions, at buildings such as Hylands School, typically run to the summer holidays, mastic included.

Before you book anyone

  • Can the work be phased to keep areas open?
  • What level of public liability insurance do they hold?
  • Will failed sealant be removed rather than covered?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

How to choose a sealant contractor

FAQs: Newney Green

Can you take on a job at a hospital such as Chelmsford and Essex Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Is a smaller place like Newney Green outside your area?

No. Places such as Newney Green are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Do we need an asbestos check before resealing?

For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder, and we will ask to see it. Suspect material is left alone until it has been tested.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Do you replace failed glazing units?

No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters on commercial buildings.

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

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Do you guarantee your work?

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

Diagnose, treat, sign off

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, then reopened once the sealant allows before we move to the next. Smaller jobs around Newney Green can be grouped with others nearby. You will have a fixed quote before work starts.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Explain the parking and delivery arrangements
  • Clear stock, furniture or equipment away from the joints
  • Tell us which areas need to stay in use
