About our mastic sealing in New Town
Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. We work on communal kitchens and washrooms, window and door perimeters on blocks and shopfronts below residential blocks, and what we are called in for most is movement joints with sealant missing and old repairs sealed over failed mastic. Whoever orders the work in New Town, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Owners and agents with buildings around smaller places such as New Town tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or email us and we will come back to it.

Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
When it isn’t the sealant
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Glazing that needs replacing
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
If in doubt, give us a call on 01277 525 020 or send photos by email and we’ll say what we think before you book.
Joints and surfaces we work on
- External wall and movement joints
- Communal entrances and stairwells
- Balcony and threshold joints
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- Shopfronts below residential blocks
Aftercare for building managers
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- List the paperwork your organisation requires when you send details
- Make mastic part of routine maintenance checks
- Group repairs into a planned programme
- Protect low-level joints in entrances
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and gives you a history.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
When to call us in New Town
Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one, the bead peels off one side.
Clients usually get in touch after noticing one or more of the following:
- Failed external movement joints
- Communal area joints that look neglected
- Brittle perimeter mastic across a building
- Mastic failing across several blocks on an estate
Trustees of buildings like St Stephen's Church can bring frame and external mastic into a planned maintenance list.
What to look for in a quote
- How the existing material will be dealt with
- How long is the guarantee, and what does it include?
- Are they CHAS accredited or on Constructionline?

Why it’s worth doing now in New Town
Failed perimeter mastic lets cold air in around frames and the windows typically get the blame. Resealing the perimeters is often the simpler fix when the frames themselves are sound. Older rural buildings around New Town move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Why choose Mastic Doctor in New Town
- Work to your specification and the manufacturer’s guidance
- Failed material removed, not covered up
- Public liability insurance in place
- Health and safety: CHAS accredited
Planned mastic for New Town portfolios
New Town lies roughly 44 miles out from central London. 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. New Town sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.
If you look after a block within reach of Pangbourne station, 1.6 miles east of New Town, frame and balcony mastic can be renewed on one programme. If your remit includes a building such as Basildon C.E. Primary School, frame and door mastic can be programmed for the holidays.

What else we do in New Town
New Town: questions and answers
Is New Town too far out for you?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you take on block-wide or estate-wide mastic work in New Town?
Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
How do you handle work on occupied blocks?
Occupiers stay in the building throughout. If any flats or units need access, we’ll tell you in advance so you can arrange it with occupiers.
Can you seal joints high up on a block?
Every block is different. We agree access with you at quote stage so there are no surprises.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Do you supply RAMS and insurance details?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
