Mastic sealing for commercial buildings in Chithurst
For blocks and buildings in Chithurst and across West Sussex, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote, and site visits can be arranged. Most enquiries involve mastic failing across several blocks on an estate and leaks at window and door perimeters, across external wall and movement joints, communal entrances and stairwells and shopfronts below residential blocks. A single leaking joint is often how a building in Chithurst first comes to us: we look at the rest while we are there and tell you what we find.
Around smaller places like Chithurst, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

On site: what to expect

Questions we are asked in Chithurst
Does your area include sites such as Midhurst Business Centre, near Chithurst?
Yes. Estates, retail parks and business parks around Chithurst, Midhurst Business Centre among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Is Chithurst off your patch?
No. Places such as Chithurst are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
How do you reach windows on upper floors?
Every block is different. We agree access with you at quote stage so the fixed quote reflects it.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Substrate edges that need repairing first
- Failed window or door frames, which need a window contractor
- Water coming in from the roof or rainwater goods
Not sure which it is? You can ring 01277 525 020 or send photos by email and we’ll tell you honestly.
Surfaces we seal
- Communal entrances and stairwells
- Balcony and threshold joints

What affects the price in Chithurst
These are the things that shape the price:
- Specialist products, such as fire-rated or hygienic sealants
- How much existing material needs removing
- Working within restricted access windows
- The site’s rules and procedures
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
What to include in your enquiry
It doesn’t need to be a full survey. These details are enough to start:
- Approximate linear metres or a joint schedule
- Anything awkward about access or site hours
- Any specification or named product
- What the building is and how it’s used
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to phone 01277 525 020 or email us.

Frames, entrances and external joints in Chithurst
Chithurst sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. Chithurst is about 46 miles from central London. Managed blocks of flats are a big part of commuter-belt property.
Blocks of flats and mixed-use buildings often cluster around stations such as Liphook station, 4.9 miles to the north of Chithurst, and their window and balcony mastic tends to age at the same rate across a building. Property owners at sites such as Midhurst Business Centre, 2.5 miles south-east of Chithurst, can have mastic renewed between lettings.
Chithurst is about 6 miles east of Petersfield, in West Sussex. Any commercial site in Chithurst is covered, whether it’s a single job or part of a planned programme. Chithurst is one of 373 places in West Sussex on our list for mastic joints. Sites around Portsmouth have their own page, about 18 miles away.

Signs you need mastic sealing in Chithurst
Previous repairs often sealed new mastic over old. New sealant won’t grip failed sealant, so these repairs rarely last.
Typical triggers for a call:
- Repeated reactive repairs to the same buildings
- Failed external movement joints
- Draught complaints from residents or tenants
- Mastic failing across several blocks on an estate
Schools and community buildings such as Stedham Primary School need frame and external mastic kept sound like any building.
What your quote should include
- Will RAMS and insurance details be available?
- Will failed sealant be removed rather than covered?
- Is the sealant right for the movement and the substrate?
- How long is the guarantee, and what does it include?
Owners, agents and contractors
For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
After the work
Once the work is signed off, a little attention goes a long way:
- Prioritise elevations facing the weather
- Avoid piecemeal callouts where you can
- Make it easy for occupiers to report draughts
- Keep a record of when each building was resealed
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and the complaints that come with it.
