About our mastic sealing in Newnham
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on communal entrances and stairwells, communal kitchens and washrooms and shopfronts below residential blocks, and what we’re called in for most is old repairs sealed over failed mastic and estate-wide sealant that is simply worn out. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Newnham is the same: the right product in a properly prepared joint.
In and around smaller places like Newnham, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or send photos by email and we’ll come back to it.

FAQs: Newnham
Is Newnham too far out for you?
Not at all. Newnham is within our area. 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 at a site such as Optrex Business Centre, by Newnham?
Yes, sites like Optrex Business Centre are within our area, along with the rest of Newnham. Send details of the unit and the work through our quote form for a quick quote.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
How do we ask for a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
What happens if it’s left?
Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish. Converted and older buildings near places like Newnham tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

How the quote is worked out
A fixed quote reflects the actual work. It allows for:
- Which sealant the job calls for
- Access and working height
- Working within restricted access windows
- How much there is to seal
Access can matter as much as the joints themselves: 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.
What we need to price the job
However big the job, the same details help:
- Any specification or named product
- Where the site is, with the postcode
- A wide shot and a close-up of the area
- Whether an asbestos survey exists
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or email drawings and photos to discuss it first.

General trades versus a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Looking after the joints
A few simple habits keep the new joints working:
- Make it easy for occupiers to report draughts
- Make mastic part of routine maintenance checks
- Keep bins and bikes away from communal door frames
- Prioritise elevations facing the weather
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first and the job grows.
Diagnose, treat, sign off
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work typically takes a few days for most blocks, with larger programmes scheduled building by building. For a building around Newnham, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

Frames, entrances and external joints in Newnham
Newnham lies roughly 41 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide. Newnham sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.
Historic properties like The Vyne, 4.6 miles west of Newnham, show the age of some local stock, where frame mastic must suit soft brick or stone. Older community buildings, Church of St. Nicholas among them, often have frames of mixed ages whose mastic varies. Landlords with units on estates such as Optrex Business Centre, 1 mile to the north of Newnham, can bring frame, door and external mastic across several units into one programme.
