Construction mastic for commercial buildings in Good Easter

Mastic tends to be one of the final packages before handover, so it lands at exactly the point the programme is tightest. We work as a mastic subcontractor to main contractors and developers, sealing plot by plot or floor by floor as areas are released. If you have cracks opening in caulked internal joints and external joints sealed in damp or cold conditions that are now failing, we can help. A single leaking joint is often how a building in Good Easter first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Sites around smaller places like Good Easter can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photos and the programme and we’ll quote to suit.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Aftercare for building managers

Once the work is signed off, a little attention goes a long way:

  • Stick to the specified sealant rather than a generic substitute
  • Don’t schedule sealing before decorators and flooring are done
  • Brief the final clean team to avoid blades near sealant
  • Plan external elevations with the weather in mind

Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead so keep them off the joints.

In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Water gets behind trays, vanity tops and panels. Proper preparation, with the right silicone first time, keeps it off the defects list.

What the job involves on each surface

Internal decorators’ caulk

Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s paintable and suits gaps that don’t move.

Window and door perimeters

Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. The specification decides which with colours matched to the frame where needed.

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

For main contractors, we work as the 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.

How the quote is worked out

A fixed quote reflects the actual work. It takes account of:

  • The site’s rules and procedures
  • Backing rod, priming and other preparation
  • The total length or number of joints
  • Removal of failed or old sealant

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What to include in your enquiry

To price the job accurately, we need to understand the site. Send us:

  • The site address and postcode
  • Asbestos survey details if the building is older
  • The type of building and who uses it
  • When you need the work done

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings that you can work with. If you have questions first, give us a call on 01277 525 020 or email a schedule or drawings.

From enquiry to sign-off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Good Easter are normally planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. First we look at the scope on site or from drawings.
  2. A fixed quote sets out scope, products and phasing.
  3. Site paperwork is confirmed and our CSCS-carded applicators are inducted.
  4. We seal plot by plot or floor by floor in line with the programme.
  5. Problems we find, such as oversized gaps, are raised straight away.
  6. Final snagging is completed and the 12-month guarantee applies.

Before we start on site

  • Tell staff and tenants when we’ll be in
  • Arrange parking or a loading space
  • Have the specification and drawings to hand

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Questions about Good Easter

Will you plan work around the academic year at somewhere like Writtle University College Cow Watering Campus?

Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is Good Easter off your patch?

Not at all. Good Easter is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you send site paperwork?

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

Can the building stay open while you work?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

When it isn’t the sealant

Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:

  • Rework caused by others damaging completed areas
  • Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
  • Frame gaps too wide for sealant, which the installer needs to correct

Not sure which it is? You can call 01277 525 020 or send photos by email and we’ll tell you honestly.

Where we work in Good Easter

  • Cladding and panel joints
  • Internal decorators’ caulk

Construction mastic in Good Easter: the local picture

Rainfall across the South East, Good Easter included, is lower than in many 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. Central London is about 28 miles from Good Easter. 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 contractors refurbishing units at places like Parklands Business Centre, 2.4 miles west of Good Easter, the mastic covers cladding panels, roller-door and window perimeters. Building work at universities like Writtle University College Cow Watering Campus, 4.1 miles south-east of Good Easter, is often timed for the summer, mastic included. Extensions at sites like Broomfield Hospital, 4.7 miles east of Good Easter, normally sit beside working departments, and the mastic follows strict access rules.
