Mastic sealing in Swanmore, done properly

For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on balcony and threshold joints, communal kitchens and washrooms and communal entrances and stairwells, and the usual reasons a site gets in touch are damaged joints in communal entrances and corridors and old repairs sealed over failed mastic. Whoever orders the work in Swanmore, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Places the size of Swanmore usually have some housing association stock, small blocks and mixed-use buildings. The mastic around their frames and external joints ages like anywhere else.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

From enquiry to sign-off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If neighbouring businesses or buildings around Swanmore need work too, visits can be combined. Tell us your site hours and we will plan around them.

  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 sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. We remove the old mastic completely and clean the joint faces back.
  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

  • Tell staff and tenants when we’ll be in
  • Share your working hours and any access restrictions
  • Arrange parking or a loading space

Advice

For owners and agents in Swanmore

Swanmore lies roughly 61 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations. Rainfall across the South East, Swanmore included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.

For agents with blocks near Botley station, which lies south-west of Swanmore, a block-wide mastic programme deals with frames, balconies and entrances in one go. Churches, halls and community buildings such as Church of St Barnabas are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Swanmore is about 6 miles east of Hedge End, in Hampshire. We cover Swanmore and the rest of Hampshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 723 places in Hampshire, large and small. Sites around Southampton have their own page, about 9 miles away.

Estate-wide resealing programmes

Consistent products and colours across an estate make future maintenance simpler and easier to manage.

Communal areas

Joints at low level in communal areas take knocks from bins, bikes and buggies and tend to fail first.

Do you need mastic sealing in Swanmore?

Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant, so these repairs rarely last.

If one of these sounds familiar, it’s time for a closer look:

  • Leaks at window and door perimeters
  • Draught complaints from residents or tenants
  • Damaged joints in communal entrances and corridors
  • Estate-wide sealant that is simply worn out

For a school such as Swanmore Church of England Aided Primary School, perimeter mastic on windows and doors is a holiday job.

What your quote should include

  • Will failed sealant be removed rather than covered?
  • How the joint faces will be prepared and primed
  • Health and safety accreditation such as CHAS
  • What level of public liability insurance do they hold?

How to choose a sealant contractor

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:

  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Misted or failed double-glazed units

If you are not sure, just call 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

What we seal

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

Common questions from Swanmore clients

Do you cover business parks and estates near Swanmore, such as Waltham Business Park?

Yes. Our area takes in Swanmore and its surroundings, with estates and business parks such as Waltham Business Park included. Send details of the unit and the work through our quote form for a quick quote.

Is Swanmore too small for you to travel to?

No. Places such as Swanmore are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

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.

What do you charge?

Every job gets its own fixed quote. To get one, call the office on 01277 525 020 or email the details over with a description of the work.

How do I request a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

How the quote is worked out

What shapes the price:

  • How accessible the joints are
  • Site requirements such as inductions and permits
  • The total length or number of joints
  • Removal of failed or old sealant

Pricing mastic joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

What to include in your enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • The type of building and who uses it
  • Approximate linear metres or a joint schedule
  • When you need the work done
  • The product your specification calls for

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or send photos by email if you’d rather talk the job through.
