Facade sealing for Upperton sites

What happens if it’s left?
The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. Converted and older buildings near places like Upperton tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Why appoint us
- Over 20 years of commercial sealing
- Colour agreed before work starts

Facade sealing in Upperton, done properly
Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits, so frosty or damp mornings can hold work back. We plan for that and keep you updated. The enquiries we see most involve damp patches beside frames after rain and air leaks through failed facade joints, on shopfront frames, coping and flashing joints and stone and brick facade joints. A specialist sealant contractor works differently from a general builder: on jobs in Upperton, preparation and product choice get the time they need.
In the countryside around places like Upperton, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Questions about Upperton
Will you take on work at estates like Hampers Common Industrial Estate, close to Upperton?
Yes. We cover Upperton and the area around it, including industrial estates, business parks and retail parks such as Hampers Common Industrial Estate. To start, just give us a call on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Is a smaller place like Upperton outside your area?
Not at all. Upperton is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
What do you charge?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we’ll price it properly.
Can weather delay the job?
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.
Will you check whether the sealant is causing the leak?
Yes. Photos are often enough to start, followed by a visit if needed. Many frame leaks are sealant failures, though not all.
What’s the quickest route to a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
When it isn’t the sealant
Some faults sit outside our scope, and we say so rather than covering them up:
- Water getting in through cracked render or porous masonry
- Joints whose design needs changing by the specifier
- Providing access systems for the work
If you’re not sure, just ring 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
Joints and surfaces we work on
- Window and door perimeters
- Stone and brick facade joints
- Cladding panel joints
- Coping and flashing joints
- Shopfront frames
- Perimeter joints where frames meet the structure
What we are called out for in Upperton
When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and the joint opens with the first real movement.
Typical triggers for a call:
- Discoloured or dirty facade joints
- Perimeter sealant that has split or peeled away
- Cold air coming in at window perimeters
- Weathered joints at frame-to-structure perimeters
With historic properties like Petworth House (1.2 miles south-east of Upperton) in the area, refurbishment work often meets old masonry that needs compatible sealants.
What to look for in a quote
- What the guarantee covers, and for how long
- How the joint faces will be prepared and primed
- Their plan for phasing and protecting the area
- Who will actually carry out the work
What the job involves on each surface
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification.
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather, so preparation and product choice matter.

Facades, frames and programmes in Upperton
Rainfall across the South East, Upperton included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. At about 42 miles from central London, Upperton is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.
New units and refits on sites such as Hampers Common Industrial Estate (to the east of Upperton) need their panel and perimeter joints sealed to the specification. For a contractor at a hotel such as The Angel Hotel (1.4 miles south-east of Upperton), the mastic often has to be finished before a reopening date.
Upperton is about 12 miles north-east of Chichester, in West Sussex. Upperton sits inside our coverage and the rest of West Sussex, with the same fixed quotes and 12-month guarantee as everywhere else.

Aftercare for building managers
Problems stay small when the joints are checked regularly. In particular:
- Never let anyone seal over old sealant
- Ask about asbestos in pre-2000 mastic
- Record the product and colour used on each elevation
- Clear debris that holds water against joints
Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards using a matching sealant.
Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and cuts time on site.
Diagnose, treat, sign off
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Jobs in and around smaller places like Upperton are normally planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Before we start on site
- Point out parking and an unloading spot
- Tell staff and tenants when we will be in
- Clear stock, furniture or equipment away from the joints
