About our mastic sealing in Swanley Village

For blocks and buildings in Swanley Village and across Kent, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. If you have a mix of products and colours from past repairs and brittle perimeter mastic across a building, we can help. Facilities teams, main contractors and managing agents in Swanley Village tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For owners with a single building near Swanley Village, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Do you need mastic sealing in Swanley Village?

Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. We will tell you if the joint edges need repairing before resealing.

Most enquiries start with one or more of the following:

  • Leaks at window and door perimeters
  • Occupiers reporting cold air round windows
  • Failed external movement joints
  • The same joint failures repeated across a portfolio

If you own or manage units on a site such as Button Street Business Park, under half a mile to the south-east of Swanley Village, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

What to look for in a quote

  • What level of public liability insurance do they hold?
  • What site paperwork they can supply
  • Their pre-qualification and accreditations
  • Whether old or failed sealant will be cut out, not overlaid

Choosing a commercial sealant contractor

Different surfaces, different methods

Planned maintenance

We can work into your cyclical maintenance plan, building by building.

Window and door perimeters on blocks

Window and door perimeters are where most mastic failure shows. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.

Questions we are asked in Swanley Village

Can work in a care setting near Swanley Village go ahead while residents are there?

Yes. We work around residents’ routines, a room or two at a time. Any site rules, from signing in to infection control, are agreed before we start.

We manage a building near Swanley station. Can you help?

Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.

How long does a typical visit take?

It depends on the scope, but the work usually takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we’ll set out a timescale with the quote.

How do you reach windows on upper floors?

It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.

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

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

What if the old mastic contains asbestos?

Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.

Aftercare for building managers

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Include mastic in your cyclical inspections
  • Ask residents or tenants to report leaks and draughts early
  • Protect low-level joints in entrances
  • Log resealing dates block by block

Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.

Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order so spending is spread.

Our process

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. For work around Swanley Village, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. A building-by-building inspection lists the failed joints.
  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

  • Arrange parking or a loading space
  • Tell us which areas need to stay in use
  • For older buildings, check the asbestos register before work

Advice

Planned mastic for Swanley Village portfolios

Swanley Village is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building normally need attention first. There are four care or nursing homes within about 2 miles of Swanley Village. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents.

If your remit includes a building such as Downsview Community Primary School, frame and door mastic can be programmed for the holidays. If you manage student housing near a university such as University of Greenwich, which lies north-east of Swanley Village, the summer turnaround is the time for mastic.

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Materials that need asbestos testing before work
  • Frames that are rotten, warped or broken
  • Water coming in from the roof or rainwater goods

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

Where we work in Swanley Village

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

Cost factors for mastic joints

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Quantities, in metres or numbers
  • Distance, for remote addresses
  • How accessible the joints are
  • The site’s rules and procedures

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What to include in your enquiry

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

  • Specification clauses that apply
  • The asbestos register, for older buildings
  • Where the site is, with the postcode
  • Rough lengths or quantities, or drawings if you have them

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or email drawings and photos to discuss it first.
