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.

Honest limits
Being straight saves everyone time. Fresh joints won’t solve:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Frames that are rotten, warped or broken
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If you’re not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Keep bins and bikes away from communal door frames
- Share your contractor requirements early
- Check sealant joints during planned building inspections
- Have the asbestos survey to hand for older buildings
Add mastic joints to your cyclical inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.
What affects the price in Greenham
These are the things that shape the price:
- Site requirements such as inductions and permits
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
- Travel to remote or island sites
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Frames, entrances and external joints in Greenham
Rainfall across the South East, Greenham included, is lower than in many parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first. At about 53 miles from central London, Greenham is within reach of the capital. 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.
Buildings close to stations like Newbury Racecourse station (0.9 miles north of Greenham) are often flats over shops, with frame mastic to keep sound. Historic properties like Shaw House (to the north of Greenham) show the age of some local stock, where frame mastic must suit soft brick or stone. If your remit includes a building such as The Willows Primary School, frame and door mastic can be programmed for the holidays.
