Facade sealing for Epping Green sites

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

How we handle facade sealing in Epping Green

Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around. If you have leaks at window and door perimeters and weathered joints at frame-to-structure perimeters, we can put it right, on perimeter joints where frames meet the structure, coping and flashing joints and window and door perimeters alike. One point of contact handles commercial sealant work in Epping Green from the first photos to the final walk-round, for single jobs and planned programmes alike.

Around smaller places like Epping Green, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Every job we finish is backed by a 12-month workmanship guarantee, in Epping Green as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Your questions answered

Can you take on a job at a hospital such as Saint Margaret's Hospital?

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

Is Epping Green too far out for you?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Do you seal facades in winter?

We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Cold, damp mornings can delay a start, and we build that into the programme.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Epping Green are usually planned as a single 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.

What we need from you

  • Share the asbestos register for older buildings
  • Flag any permit to work we will need
  • Tell us your opening times and when work is allowed

What the job involves on each surface

Brick and stone facades

Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone.

Window and door perimeters

Aluminium, PVC-U and timber frames each have their own preparation needs. We clean and prime to the sealant maker’s guidance for each surface.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Note when each elevation was last resealed
  • Combine resealing with other works that need access
  • Walk the elevations once or twice a year
  • Avoid harsh cleaners on facade sealant

Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade instead of soaking the joints.

Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading inside the building.

Do you need facade sealing in Epping Green?

Product choice matters: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Neutral-cure, facade-grade products are what most external joints need.

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

  • Draughts around frames and panels
  • Hard, chalky sealant that no longer flexes
  • Damp patches beside frames after rain
  • Previous reseals run over old sealant

Projects at schools like Epping Upland CofE Primary School work to term dates, so mastic is programmed tightly.

Choosing a commercial sealant contractor

Should maintenance staff do it?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What affects the price in Epping Green

To price the job, we consider:

  • Phasing around occupants
  • How accessible the joints are
  • Which sealant the job calls for
  • Removal of failed or old sealant

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

What we need to price the job

We can often quote from photos and a few details. Please tell us:

  • What the building is and how it’s used
  • A wide shot and a close-up of the area
  • Whether an asbestos survey exists
  • Anything awkward about access or site hours

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to phone 01277 525 020 or email a schedule or drawings with what you know.

New build and refits around Epping Green

Epping Green lies roughly 17 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes. Rainfall across the South East, Epping Green included, is lower than in many parts of the UK. 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.

Recladding or extending a unit at a site like Latton Bush Business Centre (2.2 miles north-east of Epping Green) brings panel joints and frame perimeters into the programme. Extensions at sites like Saint Margaret's Hospital, 2.6 miles south-east of Epping Green, normally sit beside working departments, and the mastic follows strict access rules.

Epping Green is about 3 miles south-west of Harlow, in Essex. We send applicators to Epping Green for facade joints. We work across 644 places in Essex, from busy centres to rural villages. London is covered too, around 17 miles from Epping Green.

Commercial sites across CM16 are covered for facade joints. Streets here include Elm Close, Epping Road and Green Close. Close to Epping Green, our area also takes in Epping Upland (1 mile south-east), Jack's Hatch (1 mile north), Broadley Common (1 mile north-west), Nazeing (2 miles north-west) and Bumble's Green (2 miles west). Bigger towns within reach include Harlow (3 miles north-east), Brentwood (12 miles south-east), Loughton (6 miles south), Waltham Abbey (4 miles south-west), Stansted Mountfitchet (13 miles north-east) and Buckhurst Hill (7 miles south).
