Mastic packages on Witham sites

Witham lies roughly 38 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. A number of hotels sit less than 2 miles from Witham. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.

When a school such as Maltings Academy is extended or refurbished, the mastic package is often squeezed into the holidays.

Witham is about 6 miles south-east of Braintree, in Essex. Commercial clients in Witham use us for work on facade joints. Across Essex, 644 places are covered, Witham among them. Our London page has more on work in that area, about 38 miles away.

For a building on Station Road, Market Lane and Guithavon Rise or nearby, send details and we’ll quote for facade joints.

About our facade sealing in Witham

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, and cold, damp starts can delay work. We build that into the programme and tell you if the forecast changes the plan. The enquiries we see most involve failed seals around shopfront and entrance frames and unsightly perimeter sealant on a visible elevation, across cladding panel joints, shopfront frames and coping and flashing joints. A specialist sealant contractor works differently from a general builder: on jobs in Witham, preparation and product choice get the time they need.

Construction in a town such as Witham is often smaller schemes: a few new flats, a school extension, a refurbished unit. A mastic package on a smaller site still needs the same care at window perimeters and facade joints.

Our workmanship is guaranteed for 12 months, in Witham as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Common questions from Witham clients

Can you keep pace with our programme in Witham?

Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can you take on a job in Witham?

Yes. London and every South East county are within our area, and Witham is part of that. Photos or drawings are enough for us to quote.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

What about RAMS and site documents?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Does the weather affect the work?

It can, for external work. 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.

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

Is old mastic on our building likely to contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first. We don’t remove asbestos-containing materials.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Joints too narrow for the movement they take, which need redesign
  • Cracked or spalling substrates that need repair before sealing

Not sure which it is? You can call the office on 01277 525 020 or email us and we’ll tell you honestly.

What we seal

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

Different surfaces, different methods

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building, so preparation and product choice matter.

Cladding panel joints

On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end to the correct depth.

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Town-centre premises in Witham may have limited parking, so tell us what’s nearby. Industrial and business units typically have yard or car park space.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Tell us what induction or permit system the site runs
  • Explain the parking and delivery arrangements

Cost factors for facade joints

Your fixed quote is built from the real scope. It allows for:

  • The size and state of each joint
  • Which sealant the job calls for
  • Quantities, in metres or numbers
  • Removal of failed or old sealant

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What we need to price the job

However big the job, these details speed things up:

  • Specification clauses that apply
  • Approximate linear metres or a joint schedule
  • Asbestos survey details if the building is older
  • Clear photos of the problem areas

To get a fixed quote, ring 01277 525 020 or email drawings and photos with the site address and an outline of the work. You can also send details through our quote form.

Common problems we fix in Witham

Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Most external joints call for a neutral-cure, facade-grade sealant.

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

  • Discoloured or dirty facade joints
  • Patch repairs that keep failing
  • Weathered joints at frame-to-structure perimeters
  • Cold air coming in at window perimeters

For a contractor at a hotel such as Spread Eagle Hotel, under half a mile south-east of Witham, the mastic often has to be finished before a reopening date.

How to choose a sealant contractor

Keeping the joints sound

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Confirm the survey covers external sealants in older buildings
  • Keep sills, gutters and drainage paths clear
  • Avoid patch repairs on failed facade joints
  • Add perimeter sealant to planned maintenance checks

Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness; record the locations.

Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading inside the building.
