Why act early in Privett
Clearing snags piecemeal is tempting when handover is close. But one planned snagging pass through each area normally clears more for less disruption, and avoids repeated visits. We can run snagging as its own phase before handover. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Why us?
- Health and safety: CHAS accredited

About our construction mastic in Privett
A typical mastic package covers more than window perimeters: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. Splitting those between trades often leaves gaps in responsibility, and one applicator team gives a consistent finish. If you’re dealing with existing joints on a refurb that need cutting out and resealing and inconsistent sealant finishes from plot to plot, we can put it right, whatever the surface. Looking for mastic applicators who cover Privett? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Conversions around smaller places like Privett often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Signs you need construction mastic in Privett
On a live site, contamination is the biggest threat to a new joint. Plaster dust, release agents, protective film residue and damp all stop sealant bonding.
Site and facilities staff are often the first to spot these:
- Frame gaps too wide for sealant alone
- Missed perimeter joints on a new elevation
- A mastic package split between trades with no clear owner
- A long mastic snag list close to completion
Building work at universities like University of Portsmouth - North Zone, 2.7 miles east of Privett, is often timed for the summer, mastic included.
What to look for in a quote
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Who will actually carry out the work
- Proof of insurance
- How they’ll work around occupants
For managing agents and facilities managers
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

What else we do in Privett
Looking after the joints
Cleaning and maintenance staff play a part too. Share these points with them:
- Brief following trades on areas that have been sealed
- Brief the final clean team to avoid blades near sealant
- Use the product the specification names
- Keep product details for future maintenance
Once an area is sealed, protect it from following trades. New beads should be left to cure before cleaning or decorating nearby, and that time depends on the product, temperature and joint depth.
Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out, and avoids a rush.
What sets the cost
To price the job, we consider:
- How accessible the joints are
- Site requirements such as inductions and permits
- How much there is to seal
- Specialist products, such as fire-rated or hygienic sealants
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
Before you send an enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- The site address and postcode
- How the joints are reached, and at what height
- Whether the building will be occupied during the work
- Approximate linear metres or a joint schedule
Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, give us a call on 01277 525 020 or email the details over.
On site: what to expect
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next.

Your questions answered
Do you take on work at healthcare sites like Gosport War Memorial Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Is Privett too small for you to travel to?
Not at all. Privett is within our area. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Can you fit around our programme?
Working to your programme, we seal each area as it’s handed over. The sequence is settled with your site team and updated as the programme moves.
Do you use the sealant named in the specification?
We use the product the specification names. Any suggested alternative is put to you before anything changes.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Construction mastic around Privett: what changes locally
With the shore within about 1 mile, Privett counts as a coastal location. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. Rainfall across the South East, Privett included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager.
Further education sites such as St Vincent College, 1.2 miles north-east of Privett, are extended and refurbished from time to time, with mastic often programmed into the summer break. Extensions at sites like Gosport War Memorial Hospital, 0.6 miles to the east of Privett, usually sit beside working departments, and the mastic follows strict access rules.
