Construction mastic across Hare Street

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Construction mastic in Hare Street, done properly

The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over, so applicators arrive when areas are genuinely ready. Sealing too early only means coming back once others have damaged it. If you have window and door perimeters that won’t pass inspection and different trades sealing to different standards, we can put it right. One point of contact handles commercial sealant work in Hare Street from the first photos to the final walk-round, for single jobs and planned programmes alike.

Construction in and around smaller places such as Hare Street 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.

A 12-month guarantee applies to all our work in Essex. Should something we installed fail, ring 01277 525 020 or send details through our quote form and we’ll come back to it.

Building and refurbishing in Hare Street

Rainfall across the South East, Hare Street included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Hare Street is about 18 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.

Hospital estates such as Suttons Manor Hospital (to the south-west of Hare Street) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Historic houses such as Hill Hall (3 miles west of Hare Street) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. For contractors refurbishing units at places like Hallsford Bridge Industrial Estate, 1.9 miles north-east of Hare Street, the mastic covers cladding panels, roller-door and window perimeters.

Hare Street is about 5 miles north-west of Brentwood, in Essex. Anywhere in CM5, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Essex, 644 places are covered, including Hare Street. Sites around London have their own page, about 18 miles away.

Anyone looking for construction mastic in CM5 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. We also cover Little End (1 mile north-east), Stanford Rivers (1 mile north), Clatterford End (1 mile north-west), Marden Ash (2 miles north-east) and Navestock Heath (2 miles south). Bigger towns within reach include Chelmsford (12 miles east), Basildon (13 miles south-east), Harlow (8 miles north-west), Brentwood (5 miles south-east), Billericay (9 miles east) and Loughton (7 miles west).

On site: what to expect

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before the next one starts. For a building around Hare Street, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. Drawings, specification and programme come to us.
  2. We take off quantities and return a fixed quote.
  3. We agree with the site team which areas come first.
  4. Plots or floors are sealed as they’re handed over.
  5. Every joint is cleaned, set to depth and sealed with the specified product.
  6. After snagging, the work is handed over under our 12-month guarantee.

Preparing the site

  • Let building users know which areas are affected
  • Send any specification or drawings in advance
  • Send asbestos survey details if the building is pre-2000

Getting a fixed quote

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

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Keep finished joints away from paint, plaster and scrapers
  • Ask cleaners to use soft cloths around fresh sealant
  • Plan external elevations with the weather in mind
  • Release areas for mastic once other trades have finished in them

At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later, and tells you what to reseal with. We can confirm the handover information you need when we quote.

External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks so external sequencing builds in some flexibility.

Why act early in Hare Street

On a refurbishment, there’s a choice between resealing existing frames and replacing them. If the frame is in good order, cutting out and resealing the perimeter can be all it needs and that’s a far smaller job. We’ll say so if a frame itself is the problem. Halls, stores and units around places like Hare Street may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote when you’re ready.

Why us?

  • Our applicators hold CSCS cards
  • Constructionline member for supplier checks
  • RAL and finish matching where the product range allows
  • A range of standard colours, depending on the product

Hare Street: questions and answers

Is hospital work, at somewhere like Suttons Manor Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Will you take on work at estates like Hallsford Bridge Industrial Estate, close to Hare Street?

Yes. We cover Hare Street and the area around it, including industrial estates, business parks and retail parks such as Hallsford Bridge Industrial Estate. To start, just call 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Is any job too small?

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

Do you cover Hare Street?

Yes. Hare Street is in our area and the rest of Essex, within our coverage of Greater London, South East England and Scotland. For a quote, give us a call on 01277 525 020 or email a schedule or drawings.

What about RAMS and site documents?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

How do I request a quote?

You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Building owners, agents and FMs in Hare Street

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

We work for building owners and managing agents on everything from one building to a spread of sites around Hare Street. One quote can cover more than one site, which keeps the paperwork simple.

How the job changes by surface

Internal decorators’ caulk

Caulk is easy to apply badly. A neat, consistent caulk line makes the decorators’ job quicker.

External facade and movement joints

Many facade substrates need a primer before sealing. Primer goes on where the sealant maker calls for it, and seal only with a dry joint inside the product’s temperature range.

What we can’t put right

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Frames fitted out of tolerance
  • Deciding which fire-stopping product a penetration needs
  • Designing joint widths or choosing the specification (that sits with the designer)

If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think.

What we seal

  • Window and door perimeters
  • Internal decorators’ caulk
  • Sanitary and kitchen joints
  • Floor and skirting junctions
  • Brick and block movement joints
  • Cladding and panel joints
