For owners and agents in Lymington

Lymington sits close to the coast, within about 1 mile. On buildings near the shore, the side facing the weather normally needs its mastic renewed first, and they deserve more regular inspection. Lymington is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building typically need attention first.

Schools and community buildings such as Lymington Junior School need frame and external mastic kept sound like any building. If you are responsible for a building such as Church of St. Thomas the Apostle, frame and door mastic needs the same attention as any other property. Buildings close to stations like Lymington Town station (0.6 miles north-east of Lymington) are often flats over shops, with frame mastic to keep sound.

Lymington is in Hampshire. Lymington sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Lymington is one of 723 places in Hampshire on our list. For work in that direction, see our Southampton page, about 13 miles away.

Mastic sealing for commercial buildings in Lymington

There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. We work on balcony and threshold joints, external wall and movement joints and shopfronts below residential blocks, and the usual reasons a site gets in touch are leaks at window and door perimeters and patchy repairs in mismatched sealant. One point of contact handles commercial sealant work in Lymington from the first photographs to the final walk-round, whether it’s one building or several.

In a town such as Lymington, buildings managed by agents and landlords range from flats over shops to small blocks and offices. Window and door perimeters, external joints and communal areas all need their mastic renewed from time to time.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Our process

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes anything from a day to a few weeks, depending on the number of buildings and joints, and we clear our waste as we work. Town-centre premises in Lymington may have limited parking, so tell us what’s nearby. Industrial and business units normally have yard or car park space.

  1. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

Preparing the site

  • Confirm the product named in the specification
  • Arrange parking or a loading space
  • Move anything stored against the joints

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Related advice

Aftercare for building managers

Problems stay small when the joints are checked regularly. Specifically:

  • Keep a record of when each building was resealed
  • Protect low-level joints in entrances
  • Ask residents or tenants to report leaks and draughts early
  • Look at the sunniest and most exposed elevations first

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.

Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.

Why act early in Lymington

Failed perimeter mastic lets cold air in around frames, and they often blame the windows. In many cases, new perimeter sealant deals with it where the frames themselves are sound. In a town such as Lymington, a lot of buildings are older and have been altered over time, so joints between old and new are often the first to go. Resealing them early protects the building behind.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

Why appoint us

  • Public liability insurance in place
  • A fixed quote before work starts
  • Commercial sealant work since 2005
  • Work carried out by CSCS-carded applicators

See what affects the cost and our accreditations and insurance.

How the quote is worked out

Each job is priced on its own details. The things that drive the figure:

  • Location, for remote and island sites
  • Induction, permit and paperwork requirements
  • Working within restricted access windows
  • Whether old sealant has to be cut out first

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Sending details for a quote

Whether it’s one area or a whole building, these details speed things up:

  • Clear photographs of the problem areas
  • Your programme or deadline
  • The site address and postcode
  • The product your specification calls for

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or send photos by email.

What we can’t put right

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Materials that need asbestos testing before work
  • Substrate edges that need repairing first
  • Glazing that needs replacing

If you are not sure, just call 01277 525 020 or use the quote form and we’ll give you a straight answer.

What we seal

  • Window and door perimeters on blocks
  • External wall and movement joints
  • Balcony and threshold joints

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

FAQs: Lymington

Does the sea air around Lymington change the choice of sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Do you work for managing agents with blocks near Lymington Town station?

Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.

How long before the joints can be used?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Do you work for managing agents and housing associations?

We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.

How long does a typical visit take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

Can you send RAMS and CSCS details before starting?

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.

Is Lymington in your area?

Yes. Lymington is in our area. For a quote, phone 01277 525 020 or send details through our quote form.
