Mastic sealing across Hareplain

Hareplain: questions and answers

Can one quote cover a number of our buildings near Hareplain?

Yes. Portfolio-wide programmes are a regular request. Send the addresses and photos and we’ll give a fixed quote.

Is Hareplain too far out for you?

No. Places such as Hareplain are covered as much as the big towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

What if the old mastic contains asbestos?

In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Can you send RAMS and CSCS details before starting?

Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.

What guarantee do you give on resealing?

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

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Our process

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes one or more days per building, depending on the joint lengths and the access, and our waste is bagged and taken away as we go. If others near Hareplain need work, visits can be combined. You will have a fixed quote before work starts.

  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.

What we need from you

  • Flag any permit to work we will need
  • Clear stock, furniture or equipment away from the joints
  • Have the specification and drawings to hand

Why act early in Hareplain

Dealing with failed joints one report at a time is slow and scattered. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. Converted and older buildings near places like Hareplain tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Why choose Mastic Doctor in Hareplain

Owners, agents and contractors

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

Planned mastic for Hareplain portfolios

Central London is about 40 miles from Hareplain. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate. Rainfall across the South East, Hareplain included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.

Around Hareplain, a planned programme renews failed mastic across a building or estate in one go. For agents with blocks near Headcorn station, 2.8 miles north of Hareplain, a block-wide mastic programme deals with frames, balconies and entrances in one go.

What the job involves on each surface

Tenement and older buildings

Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.

Planned maintenance

How long mastic lasts depends on exposure, movement and the product used. Inspecting joints regularly keeps programmes on track.

What sets the cost

What shapes the price:

  • Removal of failed or old sealant
  • Quantities, in metres or numbers
  • Distance, for remote addresses
  • The site’s rules and procedures

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Before you send an enquiry

A good diagnosis starts with the right details. Tell us:

  • Rough lengths or quantities, or drawings if you have them
  • The product your specification calls for
  • What the building is and how it’s used
  • Anything awkward about access or site hours

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Honest limits

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Misted or failed double-glazed units
  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)

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

Joints and surfaces we work on

  • Shopfronts below residential blocks
  • Communal entrances and stairwells
  • Balcony and threshold joints
