Questions we’re asked in Cadnam

Is Cadnam too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Is Mortimer Trading Estate, near Cadnam, within your area?

Yes, sites like Mortimer Trading Estate are within our area, along with the rest of Cadnam. Send details of the unit and the work through our quote form for a quick quote.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Is coloured sealant weaker than white?

Colour is a choice within a product’s range, not a separate type of sealant. Preparation, backing and tooling are what make it last.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Can wet areas have colour-matched sealant?

Yes. Sanitary silicones with anti-mould additives come in a range of colours too. We check the colour range of the sanitary product specified.

Can you seal to a brand colour across several sites?

Yes. Send the specification or colour reference and a fixed quote follows. Tell us your site hours and access windows and we’ll plan around them.

How we handle coloured sealant in Cadnam

In retail, hospitality and office fit-outs, joints are seen close up every day. A mismatched bead can make good joinery look unfinished. We pick a colour from the product’s range that sits with the finish. If you have standard-colour sealant spoiling a high-end finish and previous reseals that don’t match the original, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: in Cadnam, that means joint design, primers and backing rod as standard.

Commercial sealant work around smaller places like Cadnam tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

How the quote is worked out

To price the job, we consider:

  • Travel to remote or island sites
  • Working within restricted access windows
  • Access and working height
  • Site requirements such as inductions and permits

Pricing colour-matched joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

What we need to price the job

Diagnosis starts before we arrive. Tell us:

  • What the building is and how it’s used
  • Rough lengths or quantities, or drawings if you have them
  • Whether an asbestos survey exists
  • The product your specification calls for

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. If you have questions first, call the office on 01277 525 020 or email a schedule or drawings.

What we’re called out for in Cadnam

Joints repaired piecemeal often end up in several shades. Mixed repairs over time leave a run of mismatched joints. Doing the full run in a single colour solves it.

Look out for the following:

  • Previous reseals that don’t match the original
  • Poorly tooled joints on visible finishes
  • Joints that need to match a new RAL frame colour
  • White or grey sealant that clashes with the finish

Refits at hotels like The Bartley Lodge Hotel, under half a mile to the south of Cadnam, bring joints at vanity tops, bars and reception desks that guests see every day.

What your quote should include

  • Whether old or failed sealant will be cut out, not overlaid
  • How the joint faces will be prepared and primed
  • Is the sealant right for the movement and the substrate?
  • Are they CHAS accredited or on Constructionline?

Choosing a commercial sealant contractor

Why act early in Cadnam

People notice sealant lines more than you might expect. Putting it right costs little compared with the finishes around it, and the difference is obvious. One visit to deal with every failing joint makes more sense than several trips to a place like Cadnam. Send photos of each area and we’ll quote for the lot.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why choose Mastic Doctor in Cadnam

  • 12 months’ guarantee on every job
  • Products installed to the manufacturer’s instructions
  • A Constructionline member, so easy to vet
  • Fully insured, including public liability cover

On site: what to expect

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Jobs in and around smaller places like Cadnam are typically planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. The sealant type is chosen for the joint first, then the colour.
  2. Colour references, samples or photos of the finish are checked against the product’s range.
  3. Where colour is critical, a sample bead can be agreed in a discreet spot.
  4. We remove the existing bead, clean the faces and set the depth.
  5. We apply the agreed colour and tool it neatly, with masking where the finish needs it.

Before we start on site

  • Warn occupants and staff about the work
  • Move anything stored against the joints
  • Confirm the product named in the specification

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or email drawings and photos with what you know.

Frontages, fit-outs and joints in Cadnam

Cadnam sits in one of the drier corners of the country, the South East. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. Two named trading, business or retail sites lie within about 3 miles of Cadnam. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal; brand colours often come into it.

Industrial estates such as Mortimer Trading Estate, 2.4 miles north-east of Cadnam, have offices, trade counters and welfare areas whose sealant ages like any other building’s. Shops and cafés around stations like Ashurst New Forest station, 3.1 miles south-east of Cadnam, trade from early, so work is timed around them.

Cadnam is about 3 miles west of Totton, in Hampshire. We cover commercial sites throughout Cadnam, for single jobs and planned programmes alike. Our Hampshire coverage takes in 723 places, large and small. Our Southampton page has more on work in that area, about 8 miles away.

Anyone looking for coloured sealant in SO40 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. For a building on Old Lyndhurst Road, White Hart Lane and Southampton Road or nearby, send details and we’ll quote for colour-matched joints. Just outside Cadnam, we also work in Wittensford (1 mile west), Bartley (1 mile south-east), Copythorne (1 mile north-east), Newbridge (1 mile north) and Winsor (1 mile east). A short drive away, we cover Winchester (15 miles north-east), Eastleigh (11 miles east), Totton (3 miles east), Chandler's Ford (9 miles north-east), Hedge End (12 miles east) and Lymington (11 miles south).

Local landmarks in Cadnam

Locally, jobs take us to sites close to The White Hart pub, among other places. The closest station to Cadnam is Ashurst New Forest station, roughly 3.1 miles south-east. Other landmarks nearby include Tatchbury Mount Hospital (2.2 miles east) and National Dairy Museum (3.6 miles south-east). Green spaces nearby include Copythorne Common.

General trades versus a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Building owners, agents and FMs in Cadnam

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Cadnam can sit alongside others in a wider programme across Hampshire.

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.
