How we handle commercial sealant contractors in Street End
Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and on a working site that usually surfaces as a leak, a stain or a complaint from occupiers. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors looking after property in Street End. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. We work on kitchen worktops and splashbacks, window and door perimeters and external facade joints, and the usual reasons a site gets in touch are frame sealant that has cracked, shrunk or pulled away and gaps behind commercial kitchen worktops and sinks. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Street End is the same: the right product in a properly prepared joint.
Multi-site clients with buildings in and around Street End can put several sites on one programme, so standards and paperwork match across every site.
A job in a smaller place like Street End is usually a single building. We will want a full list and photographs first, so the right products come on the day and nothing waits for a second trip.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Honest limits
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- A dripping trap, valve or pipe behind a fitting
- Broken glass or blown double-glazed units
- Suspect materials that need testing and specialist removal
If you’re not sure, just call the office on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

What the job involves on each surface
Movement joints in walls and floors
Floor joints that take trolleys or forklifts need a tougher filler or sealant. We’ll recommend the right filler or sealant for the traffic and movement, and tell you if the edges need repairing first.
Shop fronts and retail fit-outs
Most shops can’t close for a reseal. Tell us your trading hours and access windows and we’ll plan around them, working in sections where that helps.
Common problems we fix in Street End
Every sealant joint is a maintenance item. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. On a busy commercial site several of those pile up at once.
Typical triggers for a call:
- Shrunken sealant along kitchen worktops and splashbacks
- Messy, uneven beads from earlier work that let the building down
- Frame sealant that has cracked, shrunk or pulled away
- Water staining near frames, panels or ceilings
Shops and cafés around stations like Chichester station (to the north of Street End) trade from early, so work is timed around them.
Questions to ask before you book
- Their plan for phasing and protecting the area
- Is the sealant right for the movement and the substrate?
- How joint depth will be controlled
- Health and safety accreditation such as CHAS
Street End: questions and answers
Is Enborne Business Park, near Street End, within your area?
Yes. We cover Street End and the area around it, including industrial estates, business parks and retail parks such as Enborne Business Park. Send details of the unit and the work through our quote form for a quick quote.
Does the sea air around Street End change the choice of sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.
Is Street End in your area?
Yes. We take on work across Street End, with one number for every area we cover.
How do we get a quote?
The main factors are metres of joint, removal, access, the product and how many phases there are. To get a fixed price, send details through our quote form, or phone or email us.
Our process
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. Jobs in and around smaller places like Street End are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We start with the evidence: photos, drawings or a look on site.
- A fixed quote follows, with removal and preparation included.
- Sequence, access and working times are settled before the first joint is touched.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- We hand back each area with its cure time and our 12-month guarantee.
Getting the site ready
- Agree which areas must stay open
- Share the asbestos register for older buildings
- Tell us your opening times and when work is allowed
