Mastic sealing across Maybush

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

From enquiry to sign-off

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking one or more days per building, depending on the joint lengths and the access. Work in places the size of Maybush is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.

  1. First we look at the mastic on each building and note what needs replacing.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. The programme is fixed with you, including dates you can pass on to residents or tenants.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Preparing the site

  • Let us know about inductions and permits
  • Point out any areas we must not close
  • Tell staff and tenants when we will be in

How we handle mastic sealing in Maybush

Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. The enquiries we see most involve water getting in round frames after rain and movement joints with sealant missing, across external wall and movement joints, shopfronts below residential blocks and balcony and threshold joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Maybush is the same: the right product in a properly prepared joint.

In a smaller place such as Maybush, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. The mastic around their frames and external joints ages like anywhere else.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Why it’s worth doing now in Maybush

Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. Small buildings around Maybush suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

Why appoint us

  • Health and safety: CHAS accredited
  • Workmanship guaranteed for 12 months
  • Old sealant cut out, never sealed over
  • Colours chosen to suit frames, cladding or finishes where possible

Questions we are asked in Maybush

Do you work in occupied care homes around Maybush?

Yes, with the manager deciding the order and timing of rooms. Any site rules, from signing in to infection control, are agreed before we start.

Is Northbrook Industrial Estate, near Maybush, within your area?

Yes, sites like Northbrook Industrial Estate are within our area, along with the rest of Maybush. Photos and a short description are enough for a first look.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Do you guarantee the mastic work?

Our workmanship carries a 12-month guarantee and we hold public liability insurance.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

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

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

Do you work in Maybush?

Yes. Maybush is in our area. To discuss a job, call 01277 525 020 or email a schedule or drawings.

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Planned mastic for Maybush portfolios

With the shore within about 2 miles, Maybush counts as a coastal location. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, and they deserve more regular inspection. Maybush sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building usually need attention first.

For agents with blocks near Redbridge station, 1.2 miles south-west of Maybush, a block-wide mastic programme deals with frames, balconies and entrances in one go. Trustees of buildings like St Peter's Church can bring frame and external mastic into a planned maintenance list.

Maybush is about 3 miles east of Totton, in Southampton. We cover commercial sites throughout Maybush, for single jobs and planned programmes alike. Our Southampton coverage takes in 30 places, large and small.

We take on mastic joints across the SO16 and SO15 postcode area, for business premises of every kind. We cover commercial and managed buildings on Link Road, Palm Road and Vine Road. Just outside Maybush, we also work in Coxford (1 mile north-east), Hillyfields (1 mile north-west), Regents Park (1 mile south-east), Shirley (1 mile south-east) and Millbrook (1 mile south). Bigger towns within reach include Southampton (3 miles east), Midanbury (4 miles east), Thornhill (5 miles east), Harefield (5 miles east), Itchen (4 miles south-east) and Sholing (5 miles south-east). Maybush ranks among the main centres of Southampton, with offices, shops, schools and other public and commercial buildings, and we cover them all.

What the job involves on each surface

Planned maintenance

Resealing can be scheduled alongside other planned works on a timetable you set.

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.

What we can’t put right

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Materials that need asbestos testing before work
  • Misted or failed double-glazed units
  • Failed window or door frames, which need a window contractor

If you’re not sure, just phone 01277 525 020 or send photos by email and we’ll give you a straight answer.

Joints and surfaces we work on

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

Signs you need mastic sealing in Maybush

Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits and fails early.

Clients typically get in touch after noticing something like this:

  • Movement joints with sealant missing
  • Old repairs sealed over failed mastic
  • Draught complaints from residents or tenants
  • Leaks at window and door perimeters

Landlords with units on estates such as Northbrook Industrial Estate, 1 mile to the east of Maybush, can bring frame, door and external mastic across several units into one programme.

Comparing quotes

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How long is the guarantee, and what does it include?
  • Who will actually carry out the work
  • Will failed sealant be removed rather than covered?
