About our construction mastic in Chandler's Ford

On a new build, the mastic package is one of the last trades through each area, which puts it right on the critical path. We work as a mastic subcontractor to main contractors and developers on schemes in Chandler's Ford. If you’re dealing with sealant knocked or painted over by other trades and cracks opening in caulked internal joints, we can put it right. For commercial sealant work in Chandler's Ford, you deal with one contact from quote to sign-off, whether it’s one building or several.

Older town-centre buildings in places like Chandler's Ford are often converted to new uses or extended, so new windows and cladding meet old masonry. Getting the product and primer right for both faces is what keeps those joints sound.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

What affects the price in Chandler's Ford

Quotes vary with the job. Expect it to depend on:

  • How much there is to seal
  • The site’s rules and procedures
  • Backing rod, priming and other preparation
  • Whether old sealant has to be cut out first

A quote for mastic packages depends on quantities, condition and access. Call for a quote.

Before you send an enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • Asbestos survey details if the building is older
  • Anything awkward about access or site hours
  • Whether the building will be occupied during the work
  • The site address and postcode

Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, call the office on 01277 525 020 or email us.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Designing joint widths or choosing the specification (that sits with the designer)
  • 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 the office on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Where we work in Chandler's Ford

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

Common problems we fix in Chandler's Ford

Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture, which opens up internal joints, particularly where caulk has been used in a joint that moves. Picking a flexible sealant where there’s movement keeps snags down.

What tends to prompt an enquiry:

  • Missed perimeter joints on a new elevation
  • Failed sealant in an existing building being refurbished
  • A mastic package split between trades with no clear owner
  • External joints sealed in damp or cold conditions that are now failing

Hotels like Village Hotel Club (1.4 miles south of Chandler's Ford) rarely close for long, so refurbishment mastic is phased floor by floor.

What your quote should include

  • Do they follow the manufacturer’s priming guidance?
  • Will failed sealant be removed rather than covered?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • The terms of the workmanship guarantee

Choosing a commercial sealant contractor

General trades versus a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Diagnose, treat, sign off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme, and we clear our waste as we work. Parking and loading for town-centre jobs in Chandler's Ford are worth mentioning when you send details. Industrial and business units normally have yard or car park space.

  1. We start with the drawings, specification and programme.
  2. We take off quantities and return a fixed quote.
  3. The sequence is agreed with the site manager.
  4. Each area is sealed when it’s released.
  5. Every joint is cleaned, set to depth and sealed with the specified product.
  6. Snags are cleared and the package signed off with our 12-month guarantee.

What we need from you

  • Agree which areas must stay open
  • Explain the parking and delivery arrangements
  • Tell staff and tenants when we will be in

Getting a fixed quote

Every quote starts with the facts: 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.

We’re CHAS accredited and a Constructionline member, with CSCS-carded applicators. We’re also fully insured, with five million pounds of public liability cover.

Can you work plot by plot or floor by floor?

We follow the trades through the building. Areas are sealed as they’re released by the site team.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
