Mastic sealing for businesses in Camulodunum

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

On site: what to expect

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. If you have more than one building in Camulodunum, they can often be done on the same visit, with one quote covering them. Give us your access times and we will fit the work in.

  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.
  4. The joints are prepared and resealed with the right product.
  5. Buildings are completed in turn.

What we need from you

  • Tell us your opening times and when work is allowed
  • Let building users know which areas are affected
  • Have the specification and drawings to hand

Ask for a quote

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

About our mastic sealing in Camulodunum

Owners and agents normally inherit a building’s mastic rather than choose it, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. Site teams most often ask us about complaints coming in block by block and cracked, hardened mastic round windows on a block, on balcony and threshold joints, shopfronts below residential blocks and external wall and movement joints. Most enquiries from Camulodunum start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Towns the size of Camulodunum have a mix of blocks, flats over shops and small commercial buildings looked after by agents and landlords. Window and door perimeters, external joints and communal areas all need their mastic renewed from time to time.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

What we can’t put right

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Glazing that needs replacing
  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Asbestos-containing sealant, which we don’t remove

If in doubt, call the office on 01277 525 020 or email the details over and we will say what we think before you book.

Joints and surfaces we work on

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

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Track which buildings were done and when
  • Encourage occupiers to report problems at frames
  • Reduce knocks to communal area joints
  • Group repairs into a planned programme

Log the date and extent of the resealing for each block. That makes future programmes easier to plan and gives you a history.

The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.

Camulodunum: questions and answers

Will you work in a care home in Camulodunum without moving residents out?

Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.

Will you take on work at estates like Colchester Retail Park, close to Camulodunum?

Yes, sites like Colchester Retail Park are within our area, along with the rest of Camulodunum. Send details of the unit and the work through our quote form for a quick quote.

Do you guarantee the mastic work?

There is a 12-month guarantee on our workmanship and we hold public liability insurance.

Do you seal on top of existing sealant?

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.

Do you work for managing agents and housing associations?

We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

How do I request a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Frames, entrances and external joints in Camulodunum

The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first. Four care or nursing homes sit less than 2 miles from Camulodunum. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings.

For a school such as Philip Morant School and College, perimeter mastic on windows and doors is a holiday job. If you own or manage units on a site such as Colchester Retail Park, 1 mile to the north-east of Camulodunum, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. If you manage student housing near a university such as University of Essex, which lies east of Camulodunum, the summer turnaround is the time for mastic.

We take on mastic joints across the CO3, CO2 and CO1 postcode area, whatever the building. For a building on Back Lane, Park Road and Butt Road or nearby, send details and we’ll quote for mastic joints. With the A1124 nearby, Camulodunum is straightforward for us to reach.

How the job changes by surface

External movement joints

The joint width has to suit the movement and the sealant’s capability with the width-to-depth ratio set as the manufacturer advises.

Window and door perimeters on blocks

Perimeter joints on blocks are best done elevation by elevation or block by block. Access is agreed with you before the quote is fixed.

Why deal with it now?

Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. In a town like Camulodunum, a split, stained or mouldy joint is often the first thing visitors notice. Fresh sealant makes a building look maintained.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
