Questions about Plaish
Do you cover business parks and estates near Plaish, such as Mountjoy Industrial Estate?
Yes. Estates, retail parks and business parks around Plaish, Mountjoy Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.
Is a smaller place like Plaish outside your area?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Can people stay in the building while you reseal?
Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so it can be arranged.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
How do you reach windows on upper floors?
Every block is different. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
What will the job cost?
We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Mastic sealing for commercial buildings in Plaish
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Our applicators are CSCS-carded and we hold public liability insurance. Resealed mastic joints in Plaish carry our 12-month guarantee. We work on window and door perimeters on blocks, communal kitchens and washrooms and external wall and movement joints, and the failures we are asked to look at most are the same joint failures repeated across a portfolio and leaks at window and door perimeters. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Plaish it comes down to the same thing: the right product in a properly prepared joint.
For owners with a single building near Plaish, we plan to finish in one visit where possible. Send photographs of the frames and joints and we’ll give a fixed quote.
Every job we finish is backed by a 12-month workmanship guarantee, in Plaish as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Why deal with it now?
Looking at mastic during planned maintenance costs little. Waiting until leaks appear means working under pressure and less choice about when. One visit to deal with every failing joint makes more sense than several trips to a place like Plaish. Send photos of each area and we will quote for the lot.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.
What you get with us
- One number for every site we cover
- Colours chosen to suit frames, cladding or finishes where possible
- Clear, fixed quotes
- Over 20 years of commercial sealing

Planned maintenance
Resealing can be scheduled alongside other planned works, building by building.
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
When to call us in Plaish
We often find joints filled solid with no backing rod so the mastic is bonded on three sides. It can’t stretch properly and it tears.
Most enquiries start with one or more of the following:
- Leaks at window and door perimeters
- Damaged joints in communal entrances and corridors
- Cracked, hardened mastic round windows on a block
- Repeated reactive repairs to the same buildings
Historic properties like Carisbrooke Castle (to the north-east of Plaish) show the age of some local stock, where frame mastic must suit soft brick or stone.

- Whether old or failed sealant will be cut out, not overlaid

How the quote is worked out
A fixed quote reflects the actual work. It takes account of:
- How accessible the joints are
- How much existing material needs removing
- Travel to remote or island sites
- Site requirements such as inductions and permits
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
Before you send an enquiry
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Specification clauses that apply
- What the building is and how it’s used
- Where the site is, with the postcode
- Access details, including height
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or email drawings and photos if you’d rather talk the job through.
Block-wide mastic in Plaish
The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building typically need attention first. Plaish has three care or nursing homes no more than 2 miles away. Care home owners need frame and external mastic kept sound without unsettling residents.
Site managers at schools like St Thomas of Canterbury Catholic Primary School can fit frame mastic into the summer works. If you are responsible for a building such as Church of St. Nicholas in Castro, frame and door mastic needs the same attention as any other property.
