Facade sealing in East Dean
We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure. Coping and flashing joints are included where sealant is the specified fix. If you have leaks at window and door perimeters and sealant pulling away from frames or panels, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in East Dean, preparation and product choice get the time they need.
In the countryside around places like East Dean, 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.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Why act early in East Dean
Each spell of rain drives water past a failed facade joint. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing early costs far less than repairing what the water reaches. Converted and older buildings near places like East Dean tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. If others near East Dean need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We start with photographs, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full.
- Primer goes on where the product data asks for it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- We go over the completed work with you before leaving.
What we need from you
- Explain the parking and delivery arrangements
- Flag any permit to work we will need
- Send asbestos survey details if the building is pre-2000

What affects the price in East Dean
What shapes the price:
- How much there is to seal
- How accessible the joints are
- Whether the work must be split into stages
- Distance, for remote addresses
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
What to include in your enquiry
To price the job accurately, we need to understand the site. Useful things to include:
- Any dates the work must fit around
- What the building is and how it’s used
- Approximate linear metres or a joint schedule
- Asbestos survey details if the building is older
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to give us a call on 01277 525 020 or email a schedule or drawings.
After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Confirm the survey covers external sealants in older buildings
- Check that rainwater leaves the facade the way it was designed to
- Don’t wait for a second leak before calling
- Combine resealing with other works that need access
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards using a matching sealant.
Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.
Facade sealing around East Dean: points for this area
Central London is about 49 miles from East Dean. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. East Dean sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.
For a contractor at a hotel such as Woodstock House Hotel, 1 mile to the west of East Dean, the mastic often has to be finished before a reopening date. Older buildings in the area around East Dean, such as West Dean House (2.6 miles west of East Dean), need care when sealed: the product has to suit soft or historic materials. When a college such as West Dean College of Arts and Conservation, 2.6 miles to the west of East Dean, builds or refurbishes, the mastic package typically has to fit around students and staff.

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Render or concrete edges that have broken away
- Specialist high-level access methods
- Damp caused by condensation inside the building

FAQs: East Dean
Could you schedule work at a campus like West Dean College of Arts and Conservation for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is hospital work, at somewhere like Chichester Centre, something you do?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
Do you replace failed glazing units?
No. We don’t install glazing systems, windows or glass. We seal the joints around them, such as perimeter joints where frames meet the structure.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
