Mastic sealing for Crow sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How the job changes by surface

External movement joints

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

Estate-wide resealing programmes

Priority order can follow condition, complaints or your maintenance plan. Quotes can be per block or for the full programme.

Mastic sealing for commercial buildings in Crow

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. We work on balcony and threshold joints, external wall and movement joints and communal entrances and stairwells, and the failures we’re asked to look at most are estate-wide sealant that is simply worn out and a mix of products and colours from past repairs. Whoever orders the work in Crow, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places like Crow, 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.

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

Mastic sealing in Crow: the local picture

Four care or nursing homes sit less than 2 miles from Crow. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings. Crow is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.

Site managers at schools like Ringwood Junior School can fit frame mastic into the summer works. Property owners at sites such as Platinum Jubilee Business Park (to the north-west of Crow) can have mastic renewed between lettings. Historic properties like Avon Tyrrell House, 2.4 miles south-east of Crow, show the age of some local stock, where frame mastic must suit soft brick or stone.

Crow is in Hampshire. Any commercial site in Crow is covered. Crow is one of 723 places in Hampshire on our list. For work in that direction, see our Southampton page (17 miles or so).

Site staff or a sealant specialist?

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

For managing agents and facilities managers

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

How a job runs

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Rural sites near Crow may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  3. We agree the programme and dates with you.
  4. Failed sealant is removed and the faces prepared.
  5. Joints are resealed and tooled.
  6. We check the finished work and confirm the guarantee.

Getting the site ready

  • Warn occupants and staff about the work
  • Confirm the product named in the specification
  • Explain the parking and delivery arrangements

Quotes

Cost factors for mastic joints

Quotes vary with the job. It mainly depends on:

  • Joint width, depth and condition
  • Induction, permit and paperwork requirements
  • How accessible the joints are
  • Working within restricted access windows

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Details that help us quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • The type of building and who uses it
  • Any specification or named product
  • Clear photos of the problem areas
  • The site address and postcode

To get a fixed quote, ring 01277 525 020 or email a schedule or drawings with the site address and an outline of the work. Our quote form is another easy route.

Keeping the joints sound

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Prioritise elevations facing the weather
  • Share your contractor requirements early
  • Keep a record of when each building was resealed
  • Make mastic part of routine maintenance checks

Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.

Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first and the job grows.

Crow: questions and answers

Is Crow too far out for you?

No. Small places get the same service as large ones. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Will you take on work at estates like Platinum Jubilee Business Park, close to Crow?

Yes, sites like Platinum Jubilee Business Park are within our area, along with the rest of Crow. Photos and a short description are enough for a first look.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Do you work for managing agents and housing associations?

Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.

What guarantee do you give on resealing?

Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.

What paperwork can you provide?

Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
