How we handle mastic sealing in New Marston
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. We work on communal entrances and stairwells, balcony and threshold joints and external wall and movement joints, and the usual reasons a site gets in touch are cracked, hardened mastic round windows on a block and repeated reactive repairs to the same buildings. Looking for mastic applicators who cover New Marston? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Older buildings and conversions around places like New Marston mix old masonry with newer frames. Perimeter joints need a sealant that suits both frame and masonry.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

FAQs: New Marston
Can you work in a care home near New Marston with residents in?
Yes. We work around residents’ routines, a room or two at a time. We follow the home’s own procedures throughout.
Is a smaller place like New Marston outside your area?
No. Places such as New Marston are covered as much as the big towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
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’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
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.

Common problems we fix in New Marston
UV and rain age external sealant. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
Things that normally lead to an enquiry:
- Failed external movement joints
- Old repairs sealed over failed mastic
- The same joint failures repeated across a portfolio
- Communal area joints that look neglected
Older community buildings, Saint Michael and All Angels among them, often have frames of mixed ages whose mastic varies.
Questions to ask before you book
- The named product and why it was chosen
- Can the work be phased to keep areas open?
- Their public liability cover
- Who will actually carry out the work
Cost factors for mastic joints
What shapes the price:
- Quantities, in metres or numbers
- Distance, for remote addresses
- Any access equipment needed
- Joint width, depth and condition
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Details that help us quote
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Whether the building will be occupied during the work
- Photos of the joints, close up and from further back
- Any specification or named product
- The site address and postcode
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
Our process
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a site in New Marston, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.
- We check the asbestos register for older buildings and look at the joints.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
Preparing the site
- Point out parking and an unloading spot
- Move anything stored against the joints
- Tell us what induction or permit system the site runs

Different surfaces, different methods
Tenement and older buildings
Older mastic can contain asbestos, so we check the asbestos register or survey first. Suspect material is tested before work continues.
Commercial and mixed-use buildings
Commercial buildings have mastic at shopfronts, entrances and external joints. A planned programme suits multi-building portfolios.
Keeping the joints sound
Cleaning and maintenance staff play a part too. Share these points with them:
- Have the asbestos survey to hand for older buildings
- Track which buildings were done and when
- Avoid piecemeal callouts where you can
- Make mastic part of routine maintenance checks
Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order and work down the list.
