How we handle commercial sealant contractors in Norton
Mastic Doctor has been sealing joints for businesses and contractors since 2005, and the paperwork side is in order: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. If your site needs RAMS, an insurance certificate or CSCS details, say so and we will confirm with the quote. We work on window and door perimeters, external facade joints and movement joints in walls and floors, and the failures we are asked to look at most are greasy, split joints in a kitchen or tea point and smeared sealant across finishes from a rushed job. A specialist sealant contractor works differently from a general builder: in Norton, that means joint design, primers and backing rod as standard.
If you look after more than one building near Norton, the work can be planned as one programme, so standards and paperwork match across every site.
Work in smaller places such as Norton tends to come one building at a time: a pub kitchen, a hall, a small office. We’ll want a full list and photographs first, so the right products come on the day and nothing waits for a second trip.
Every job we finish is backed by a 12-month workmanship guarantee, in Norton as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Common questions from Norton clients
Do you cover business parks and estates near Norton, such as Chichester Business Park.?
Yes. Our area takes in Norton and its surroundings, with estates and business parks such as Chichester Business Park. Included. To start, just ring 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Is Norton too far out for you?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Is it OK to apply fresh sealant over existing beads?
Removal comes first, every time. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.
Can you handle sealant work across several sites?
Yes, we can. Send a list of addresses and what’s needed at each, and we’ll put together a fixed quote and a sensible order of work.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
How long does a job like this take?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
Other services in Norton
Leave it or put it right?
Putting off a reseal normally moves the cost rather than avoiding it. Water past a frame perimeter or a washroom joint can reach plasterboard, insulation, floor coverings and the ceiling below. Resealing while only the sealant has failed keeps the job small. Halls, stores and units around places like Norton may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

Norton has three care or nursing homes no more than 2 miles away. Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound, often in colours that suit the décor. At least three named trading, business or retail sites lie within about 3 miles of Norton. Sites like these see regular refits, with shopfronts, offices and staff areas to seal, often in a colour the occupier specifies.
Parks like Chichester Business Park. (1.2 miles west of Norton) see tenants come and go, and every move-in brings joints to seal. Premises within reach of Barnham station (2.3 miles south-east of Norton) often have busy frontages where joints are seen by everyone passing.

What sets the cost
Each job is priced on its own details. The main factors are:
- Distance, for remote addresses
- The size and state of each joint
- Any access equipment needed
- Which sealant the job calls for
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Sending details for a quote
It doesn’t need to be a full survey. These details are enough to start:
- The site address and postcode
- Any dates the work must fit around
- Whether the building will be occupied during the work
- A wide shot and a close-up of the area
Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, phone 01277 525 020 or send details through our quote form.
Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Check sealant as part of routine building inspections
- Make sure contractors see the asbestos survey before cutting out old mastic
- Brief cleaning contractors to avoid scourers and blades on sealant
- Make sure ventilation in wet areas is switched on and working
Later works are the usual way new joints get damaged. When fittings are moved or cabling added, the sealant nearby is easily disturbed and the joint gets left open. Where work has disturbed a joint, just call the office on 01277 525 020 or send details through our quote form for a quote.
Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.
Our process
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Norton need work, visits can be combined. You will have a fixed quote before work starts.
- We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations, and a site visit is booked where it helps.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- Site hours, access windows and the order of areas are agreed before we start.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- We walk the completed areas with you and sign them off under the 12-month guarantee.
Before we start on site
- Warn occupants and staff about the work
- Let us know about inductions and permits
- Send asbestos survey details if the building is pre-2000

Advice
For managing agents and facilities managers
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Norton can sit alongside others in a wider programme across West Sussex.
Do you need commercial sealant contractors in Norton?
External sealant takes a steady beating from the weather. UV hardens the surface while wind and rain work at the edges. A hardened bead can’t follow the building any more.
Any of the following is a good reason to get the joints checked over:
- Shrunken sealant along kitchen worktops and splashbacks
- Black mould through washroom sealant that won’t clean off
- A top-up bead over failed sealant, now lifting
- Damp patches where an external joint has failed
Sites a few miles apart, such as Chichester Business Park. And The Woodhorn Business Centre, can share one programme and one point of contact.
