How we handle mastic sealing in Nyetimber
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card and we hold public liability insurance. Resealed mastic joints in Nyetimber carry our 12-month guarantee. We work on shopfronts below residential blocks, external wall and movement joints and window and door perimeters on blocks, and the failures we’re asked to look at most are damp patches beside frames and movement joints with sealant missing. Looking for mastic applicators who cover Nyetimber? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
In a smaller place such as Nyetimber, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. Their window perimeters and external joints need renewing as the mastic ages.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email a schedule or drawings and we’ll arrange a return visit.

Common problems we fix in Nyetimber
Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear most of all on the sunniest and most exposed elevations.
What tends to prompt an enquiry:
- Damaged joints in communal entrances and corridors
- Movement joints with sealant missing
- Repeated reactive repairs to the same buildings
- Damp patches beside frames
Student accommodation around universities such as University of Chichester (to the north of Nyetimber) is typically managed block by block, which suits a planned mastic programme.

What else we do in Nyetimber
Owners, agents and contractors
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
On site: what to expect
Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. If neighbouring businesses or buildings around Nyetimber need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- We check the finished work and confirm the guarantee.
Getting the site ready
- Agree which areas must stay open
- Send asbestos survey details if the building is pre-2000
- Share your working hours and any access restrictions

- Roof leaks, gutters or failed flashings that aren’t sealant joints

Common questions from Nyetimber clients
Does a coastal location like Nyetimber affect which sealant is used?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Is Enborne Business Park, near Nyetimber, within your area?
Yes. Our area takes in Nyetimber and its surroundings, with estates and business parks such as Enborne Business Park included. A few photos and the unit address let us price the work.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Do you do block-wide mastic programmes?
Yes. We survey and price each building, then work through them in order starting wherever is most urgent.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
What sets the cost
A fixed quote reflects the actual work. It takes account of:
- Access and working height
- Removal of failed or old sealant
- Backing rod, priming and other preparation
- Phasing around occupants
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Sending details for a quote
Diagnosis starts before we arrive. Let us know:
- Any dates the work must fit around
- Anything awkward about access or site hours
- Whether an asbestos survey exists
- Photos of the joints, close up and from further back
To get a fixed quote, ring 01277 525 020 or email the details over with the site address and an outline of the work. You can also send details through our quote form.
Looking after buildings in and around Nyetimber
Nyetimber lies within about 1 mile of the sea. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do; plan inspections around that. Nyetimber sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.
For owners of several units at places like Enborne Business Park, 2.5 miles to the west of Nyetimber, one programme can deal with frame and external mastic across the lot. Site managers at schools like Rose Green Infant School can fit frame mastic into the summer works.
