Mastic sealing near Bartley

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

Honest limits

Honesty saves time and money. Fresh joints won’t solve:

  • Masonry that has broken away beside the joint
  • Glazing that needs replacing
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first

If you are not sure, just call 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Joints and surfaces we work on

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

Mastic sealing in Bartley, done properly

Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Entrances and stairwells are kept in use while we work. If you have occupiers reporting cold air round windows and worn sealant at communal door frames, we can help. A specialist sealant contractor works differently from a general builder: in Bartley, that means joint design, primers and backing rod as standard.

Rural conversions near places like Bartley often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

How a job runs

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Bartley are usually planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  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

  • Let us know about inductions and permits
  • Make sure the joints can be reached

Advice

After the work

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Start inspections with the most exposed faces
  • Keep bins and bikes away from communal door frames
  • Include mastic in your cyclical inspections
  • Make it easy for occupiers to report draughts

Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.

Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and saves internal repairs.

Why it’s worth doing now in Bartley

Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows, and the complaints come with it. Around Bartley, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Planned mastic for Bartley portfolios

Rainfall across the South East, Bartley included, is lower than in many parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first. Two care or nursing homes sit less than 2 miles from Bartley. Care home owners need frame and external mastic kept sound without unsettling residents.

If you look after a block within reach of Ashurst New Forest station (2.2 miles south-east of Bartley), frame and balcony mastic can be renewed on one programme. For a school such as Bartley Church of England Junior School, perimeter mastic on windows and doors is a holiday job.

Bartley is about 2 miles west of Totton, in Hampshire. We cover commercial sites throughout Bartley, whether it’s a single job or part of a planned programme. Bartley is one of 723 places we cover in Hampshire. Our Southampton page has more on work in that area.

Do you need mastic sealing in Bartley?

Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.

Any of the following is a good reason to get the joints checked over:

  • Failed external movement joints
  • Damaged joints in communal entrances and corridors
  • Patchy repairs in mismatched sealant
  • Brittle perimeter mastic across a building

If you own or manage units on a site such as Mortimer Trading Estate, 2.4 miles to the north of Bartley, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Questions to ask before you book

  • Will RAMS and insurance details be available?
  • How the joint faces will be prepared and primed
  • Will failed sealant be removed rather than covered?
  • How they’ll work around occupants

Questions about Bartley

We manage a building near Ashurst New Forest station. Can you help?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.

Does your area include sites such as Mortimer Trading Estate, near Bartley?

Yes. Estates, retail parks and business parks around Bartley, Mortimer Trading Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Do you work in Bartley?

Yes. Bartley is in our area and the rest of Hampshire. To discuss a job, give us a call on 01277 525 020 or email us.

How do you handle work on occupied blocks?

We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.

How long do sealant joints last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Can you send RAMS and CSCS details before starting?

We’re CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
