Construction mastic across Shalmsford Street

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

Construction mastic in Shalmsford Street

We work to the specification and the programme rather than whatever product is to hand. Where the specification names a product, we use it, and if an alternative is proposed, it goes to you for acceptance first. Backing, primer and depth follow what the sealant maker sets out, so the joints perform as the designer intended. If you are dealing with frame gaps too wide for sealant alone and sanitary sealant damaged by following trades, we can put it right. Whoever orders the work in Shalmsford Street, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

On a small site around Shalmsford Street, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we will plan around those stages.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or email drawings and photos and we’ll come back to it.

Shalmsford Street: questions and answers

Is Shalmsford Street too far out for you?

No. Places such as Shalmsford Street are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Is Stour Valley Business Park, near Shalmsford Street, within your area?

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

Do you take on mastic snagging only?

Yes. Snag-only work is something we take on.

Can fire-rated sealing at service penetrations be included?

It can be part of the package where specified. Tell us what records you need and we’ll confirm with the quote.

Can you seal external joints in wet or cold weather?

External mastic depends on conditions: the joint needs to be dry and within the product’s temperature range. External work is sequenced with some flexibility.

How do we ask for a quote?

You can use the quote form on this site; alternatively, call the office on 01277 525 020 or email us. Include photographs or drawings if you have them.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

When something else is needed

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Frame gaps too wide for sealant, which the installer needs to correct
  • Approving fire stopping as compliant
  • Rework caused by others damaging completed areas

If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

Joints and surfaces we work on

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

When to call us in Shalmsford Street

Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens so we set the depth properly before sealing.

What tends to prompt an enquiry:

  • Perimeter gaps outside the sealant’s range
  • A long mastic snag list close to completion
  • Window and door perimeters that won’t pass inspection
  • External joints sealed in damp or cold conditions that are now failing

Extensions at sites like Kent and Canterbury Hospital, 3.2 miles east of Shalmsford Street, normally sit beside working departments, and the mastic follows strict access rules.

Questions to ask before you book

  • Is the sealant right for the movement and the substrate?
  • Health and safety accreditation such as CHAS
  • Proof of insurance
  • Whether their applicators hold CSCS cards

Questions to ask before you appoint anyone

Owners, agents and contractors

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.

On site: what to expect

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. For a job in Shalmsford Street, the main thing is a clear picture of the work. A fixed quote follows.

  1. We price from the drawings, specification and programme you send.
  2. You receive a fixed quote listing scope, products and phasing.
  3. Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
  4. We seal each plot or floor as it’s released to us.
  5. Each joint is prepared, backed to depth and sealed in the product the specification names.
  6. Snags are cleared before handover and completed areas carry our 12-month guarantee.

Preparing the site

  • Arrange parking or a loading space
  • Tell us your opening times and when work is allowed
  • Send asbestos survey details if the building is pre-2000

What affects the price in Shalmsford Street

The price varies from site to site. It mainly depends on:

  • Backing rod, priming and other preparation
  • The total length or number of joints
  • Any access equipment needed
  • Working within restricted access windows

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

What we need to price the job

Diagnosis starts before we arrive. Let us know:

  • Asbestos survey details if the building is older
  • Specification clauses that apply
  • Your programme or deadline
  • Approximate linear metres or a joint schedule

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or call 01277 525 020 or send photos by email if you’d rather talk the job through.

Building and refurbishing in Shalmsford Street

Shalmsford Street is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack. Shalmsford Street lies roughly 51 miles out 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.

For a contractor at a hotel such as Howfield Manor Hotel (1.2 miles north-east of Shalmsford Street), the mastic often has to be finished before a reopening date. On a campus such as University of the Creative Arts (3.5 miles north-east of Shalmsford Street), new teaching buildings and residences are usually built and refurbished around the academic year.

Shalmsford Street is about 3 miles south-west of Canterbury, in Kent. If you are looking for construction mastic in Shalmsford Street, we can help, as we do across Kent. Shalmsford Street is one of 931 places in Kent on our list. There’s a separate page for London, about 51 miles away.

Just outside Shalmsford Street, we also work in Chartham (1 mile north), Mystole (1 mile west), Garlinge Green (1 mile south), Chartham Hatch (1 mile north) and Thanington (2 miles north-east).

A little further out are Chilham Castle (2.6 miles west) and Whitefriars Shopping Centre (3.3 miles north-east). For a walk, there’s Blean Woods RSPB Reserve.

After the work

A few simple habits keep the new joints working:

  • Keep scrapers and abrasive pads off new beads
  • Record the products used in the O&M file
  • Plan external elevations with the weather in mind
  • Get the mastic subcontractor involved early in the programme

Record which products went where in the handover file. Future maintenance is easier when the products are known and avoids guesswork when joints are renewed. Tell us what records you need and we will confirm with the quote.

Snag items left to the last week put handover at risk. A planned close-out through each area as it completes keeps the list short and keeps handover on track.
