What sealant work can’t fix
Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:
- Deciding which fire-stopping product a penetration needs
- Designing joint widths or choosing the specification (that sits with the designer)
- Oversized gaps that need packing or adjustment by others
If you’re not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
What we seal
- Internal decorators’ caulk
- Brick and block movement joints
- Window and door perimeters
- Cladding and panel joints
- Floor and skirting junctions
- Sanitary and kitchen joints
About our construction mastic in Park Gate
Site managers want applicators who turn up with the right cards and paperwork. We are a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we’re fully insured. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. The enquiries we see most involve missed perimeter joints on a new elevation and internal caulk splitting as the building dries out, across window and door perimeters, internal decorators’ caulk and sanitary and kitchen joints. Searching for sealant specialists in Park Gate? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
In the countryside around places like Park Gate, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Can you work on a hospital site such as Fareham Community Hospital?

Do you do internal caulk as well as external mastic?
Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens, all priced as one package.
Can the building stay open while you work?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Are you insured?
Yes. We’re fully insured, and the certificate can go with your quote.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Diagnose, treat, sign off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates, and our waste is bagged and taken away as we go. If others near Park Gate need work, visits can be combined. You’ll have a fixed quote before work starts.
- Drawings, the sealant specification and your programme come to us for pricing.
- A fixed quote sets out the scope, the products and the sequence.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
Preparing the site
- Share your working hours and any access restrictions

Related advice
Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Sites and facades in and around Park Gate
Park Gate sits close to the coast, within about 3 miles. Coastal exposure means perimeter and cladding joints work harder than on an inland job, and the sealant, primer and backing need choosing with that in mind. The area within 2 miles of Park Gate holds several hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
New units and refits on sites such as Park Gate Business Centre, under half a mile to the north of Park Gate, need their panel and perimeter joints sealed to the specification. For a contractor at a hotel such as Solent Hotel and Spa (0.9 miles north-east of Park Gate), the mastic often has to be finished before a reopening date. Projects at schools like Park Gate Primary School work to term dates, so mastic is programmed tightly.

What the job involves on each surface
Fire-rated sealant where specified
Not every penetration suits a sealant. Other products are used for some services and gaps. Record requirements are agreed with the quote.
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Each joint is prepared, sealed and finished with a neat tooled line, and any bath is loaded with water first where that’s the agreed method.
Why it’s worth doing now in Park Gate
Clearing snags piecemeal is tempting when handover is close. But one planned snagging pass through each area typically clears more for less disruption. We can run snagging as its own phase before handover. Converted and older buildings near places like Park Gate tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.
