Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. 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. If you have worn sealant at communal door frames and brittle perimeter mastic across a building, we can put it right. Looking for mastic applicators who cover Caversham Heights? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Converted and older buildings in and around Caversham Heights often put modern windows into old walls. The mastic there needs to suit both surfaces.

Questions about Caversham Heights
Does your area include sites such as The Station Shopping Park, near Caversham Heights?
Yes. Our area takes in Caversham Heights and its surroundings, with estates and business parks such as The Station Shopping Park included. A few photographs and the unit address let us price the work.
Is Caversham Heights too small for you to travel to?
Not at all. Caversham Heights 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.
How do you reach windows on upper floors?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we’ll confirm the approach in the quote.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
What guarantee do you give on resealing?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
What will the job cost?
Each job is quoted on its own details. For yours, speak to us on 01277 525 020 or email us.
Who decides which product is used?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How the quote is worked out
To price the job, we consider:
- Whether the work must be split into stages
- Location, for remote and island sites
- The size and state of each joint
- The product specified
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.
Details that help us quote
For an accurate fixed quote, we need to understand the site. Send us:
- Approximate linear metres or a joint schedule
- The site address and postcode
- Whether the building will be occupied during the work
- Clear photographs of the problem areas
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email drawings and photos.

Mastic sealing in Caversham Heights: the local picture
Caversham Heights lies roughly 39 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.
Site managers at schools like Caversham Primary School can fit frame mastic into the summer works. If you are responsible for a building such as St. Andrew's Church, frame and door mastic needs the same attention as any other property.

Any of the following is a good reason to get the joints checked over:

What sealant work can’t fix
Some faults sit outside our scope, and we say so rather than covering them up:
- Glazing that needs replacing
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Failed window or door frames, which need a window contractor
If in doubt, call the office on 01277 525 020 or email the details over and we will say what we think.
Joints and surfaces we work on
- Balcony and threshold joints
- Shopfronts below residential blocks
- Communal entrances and stairwells
- Window and door perimeters on blocks
- External wall and movement joints
- Communal kitchens and washrooms
Should maintenance staff do it?
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
