Signs you need mastic sealing in Nutbourne
Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope and fails early.
Typical triggers for a call:
- Brittle perimeter mastic across a building
- Movement joints with sealant missing
- Mastic failing across several blocks on an estate
- Patchy repairs in mismatched sealant
Historic properties like Old Place Manor (to the west of Nutbourne) show the age of some local stock, where frame mastic must suit soft brick or stone.

How we handle mastic sealing in Nutbourne
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Resealed mastic joints in Nutbourne carry our 12-month guarantee. If you have water getting in round frames after rain and window mastic that has split and shrunk, we can help. Facilities teams, main contractors and managing agents in Nutbourne tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Rural conversions near places like Nutbourne often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Failed window or door frames, which need a window contractor
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Misted or failed double-glazed units
If you are not sure, just call the office on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.
What we seal
- Balcony and threshold joints
- External wall and movement joints

What the job involves on each surface
Planned maintenance
We can work into your cyclical maintenance plan on a timetable you set.
Commercial and mixed-use buildings
Mixed-use buildings combine shops below with flats or offices above, so phasing has to suit both. Tell us your site hours and access windows and we will plan around them.
After the work
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Protect low-level joints in entrances
- Check the asbestos register before any old mastic is disturbed
- Group repairs into a planned programme
- Ask residents or tenants to report leaks and draughts early
If a joint we sealed fails within 12 months, tell us and we’ll look at it. After that, regular inspection keeps the programme on track.
One failed perimeter typically means others on the same building are close, so it pays to look at the whole elevation. A planned reseal saves repeated visits.
Common questions from Nutbourne clients
Is Nutbourne too small for you to travel to?
Not at all. Nutbourne is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Do you work for managing agents with blocks near Pulborough station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Can you take on resealing for a block portfolio?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
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.
Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking one or more days per building, depending on the joint lengths and the access. Smaller jobs around Nutbourne can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

Advice
Blocks and managed buildings in Nutbourne
Nutbourne is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building typically need attention first. Nutbourne is about 41 miles from central London. Managed blocks of flats are a big part of commuter-belt property.
Trustees of buildings like St Mary's Church can bring frame and external mastic into a planned maintenance list. For owners of several units at places like Broomers Hill Business Park, which lies north-west of Nutbourne, one programme can deal with frame and external mastic across the lot.
