Mastic sealing for businesses in Workhouse Hill

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

Surface by surface

Commercial and mixed-use buildings

Commercial occupiers normally stay open during the work, so we plan around them.

External movement joints

Brickwork, blockwork and panel joints let a building move. Once that sealant goes, rain can reach the wall.

Mastic sealing in Workhouse Hill, done properly

Managing agents and housing associations usually need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. If you’re dealing with repeated reactive repairs to the same buildings and damp patches beside frames, we can put it right, on window and door perimeters on blocks, external wall and movement joints and communal entrances and stairwells alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Workhouse Hill, preparation and product choice get the time they need.

Around smaller places like Workhouse Hill, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

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:

  • Materials that need asbestos testing before work
  • Leaks from above rather than through a joint
  • Leaks through the frame itself rather than the perimeter

If you’re not sure, just phone 01277 525 020 or email us and we’ll give you a straight answer before you book.

Surfaces we seal

  • Window and door perimeters on blocks
  • Communal kitchens and washrooms
  • Communal entrances and stairwells
  • Balcony and threshold joints
  • External wall and movement joints
  • Shopfronts below residential blocks

Common questions from Workhouse Hill clients

Will you take on a block within reach of Colchester station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.

Will you take on work at estates like Langham Barns Business Centre, close to Workhouse Hill?

Yes, sites like Langham Barns Business Centre are within our area, along with the rest of Workhouse Hill. Photos and a short description are enough for a first look.

Do you work for managing agents and housing associations?

Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn so you can plan around it.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Can you seal joints high up on a block?

It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.

Can you plan resealing across several buildings?

Yes. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.

Looking after buildings in and around Workhouse Hill

Workhouse Hill is about 53 miles from central London. Within reach of London, blocks run by agents and associations are common around stations. Rainfall across the South East, Workhouse Hill included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.

For a school such as Boxted St Peter's Church of England School, perimeter mastic on windows and doors is a holiday job. For owners of several units at places like Langham Barns Business Centre, which lies south-east of Workhouse Hill, one programme can deal with frame and external mastic across the lot. If you’re responsible for a building such as Church of St Peter, frame and door mastic needs the same attention as any other property.

Why it’s worth doing now in Workhouse Hill

Draughts round window perimeters cost occupiers comfort and the windows normally get the blame. Resealing the perimeters is often the simpler fix where the frames themselves are sound. For buildings around smaller places like Workhouse Hill, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why clients in Workhouse Hill choose us

  • 12-month guarantee on workmanship
  • CSCS-carded applicators
  • Sealing commercial buildings since 2005
  • Coloured sealants to suit the setting, where available

Read how commercial sealant jobs are priced and our accreditations.

What sets the cost

To price the job, we consider:

  • Induction, permit and paperwork requirements
  • Joint width, depth and condition
  • Phasing around occupants
  • The product specified

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

Details that help us quote

A good diagnosis starts with the right details. Tell us:

  • When you need the work done
  • Photos of the joints, close up and from further back
  • What the building is and how it’s used
  • Rough lengths or quantities, or drawings if you have them

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or call the office on 01277 525 020 or send photos by email if you’d rather talk the job through.

Should maintenance staff do it?

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Our process

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact. Rural sites near Workhouse Hill may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We check the asbestos register for older buildings and look at the joints.
  2. The products and programme are set out in a fixed quote.
  3. Failed mastic is removed completely.

Getting the site ready
