Chimney surveys for homes and businesses in Crosspost
Many homes have chimneys that are no longer used. Even when it is not used, a stack has to stay weathertight. Capping a stack without ventilation can trap moisture and lead to damp inside. We check how redundant stacks have been capped and look for damp in the chimney breasts. You get photos of each stack and our recommendations. If you’ve noticed gaps in the mortar around the pots and damp patches on chimney breasts, a survey will tell you what’s going on, on chimney pots and cowls, shared and party-wall stacks and lead flashings alike.
Somewhere as small as Crosspost, homes are frequently older cottages and farmhouses, with outbuildings and some newer houses. Older roofs may be clay tile, slate, stone or thatch, frequently with chimneys that have stood a long time. We report on what can be seen safely, and thatch is a specialist material. Chimneys and lead flashings on old roofs often need the most attention.
Where we cannot see part of the chimney stack, the report says so. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

Common roof problems in Crosspost
Chimney stacks stand above the roof, exposed to wind, rain and frost on every side. Frost opens up cracks in the mortar, and rain gets into worn bricks and joints. People normally call us when they notice damp or a problem with the stack, or before a purchase.
People normally book a survey after spotting something like this:
- Flashings pulling away from the stack
- Bricks with flaking faces
- Eroded joints in the brickwork
- Loose, cracked or missing pots
If your house is among the older ones in the streets near St Mary Magdalene's Church, old fixings, lead flashings and tall chimneys are typical of older roofs.

What affects the price in Crosspost
When we price a survey, we consider:
- How complicated the roof is, with its valleys, chimneys and parapets
- Whether it’s a home or a commercial building
- How tall the building is and how easy the roof is to see
- Basic, Standard or Premium
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, with VAT included. The roof’s size, height and access matter as well.
Booking your survey
Before you get in touch, it is useful to have:
- Where water is showing inside, if it is
- When you need the report by
- Anything about access we should know
- Pictures from the garden or a window, if you have them
Once you know what you need, phone 07833 053749 or drop us an email. From there it’s a case of choosing a package, agreeing the price and fixing a day, weekday or weekend.
Crosspost homes and their roofs
In Sussex, older roofs are often handmade clay tile, frequently with tile-hanging on the walls below. A few old Sussex buildings still carry heavy Horsham stone slabs. Whatever the covering, it’s often the fixings, flashings, valleys and gutters that give out first. About 3.1 miles north-east lies Ockenden Manor, a reminder of how long the area around Crosspost has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
If you let a flat or house near Wivelsfield station, knowing the condition of the roof, chimneys and gutters helps you plan work rather than react to complaints. Anyone responsible for a site like Bolney CofE Primary School will know that long gutter runs and wide roofs on a building that size are worth checking on a regular cycle.

Roof by roof
Lead flashings
Where the chimney meets the roof slopes, lead flashings keep water out. We check for lifting, splits and gaps in the joints.
Rendered stacks
Water can get in through cracks and then struggle to dry out. Cracks are photographed and noted.
How it works
Every roof is different; as a rough guide, the survey takes between one and two hours at most homes, rising to roughly 3–4 hours on a commercial building. If you have questions on the day, just ask. Cottages and farmhouses around Crosspost frequently have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can be seen safely.
- You tell us whether any stacks are shared, unused or leaning.
- We check the roof around each stack, including the flashings.
- We check the flaunching and pots on every stack.
- We note the brickwork, pointing and any sign of leaning.
- You receive a written report setting out what needs attention first.

Questions from Crosspost
Can a landlord with a rental near Wivelsfield station book a roof survey?
Yes, landlords and agents are among the people we work for. You can ring 07833 053749 or email us with the address and what you need, and we will talk through which survey suits.
Do you cover smaller places like Crosspost?
Yes. Crosspost is within the area we cover, which takes in towns, villages and rural addresses. We survey roofs across London and South East England. Let us know about access, parking and anything unusual about getting there when booking.
Do you survey on Saturdays and Sundays?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Let us know which days suit you as you book.
What happens after the survey?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Will you check the chimney is safe to use with a fire?
No. A flue inspection, sweep or gas safety check is a separate job. We look at the stack, pots, flaunching, pointing and flashings, and damp inside and flag anything that suggests the flue needs a look.
Does this replace a RICS home survey?
No. It is a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
Can you inspect my roof with a drone?
Where it’s applicable and safe, yes. We fly a sub-250g drone and we are a CAA-registered drone operator (Flyer ID and Operator ID). Drone inspection is part of the Drone Roof Survey and the Premium Survey, where applicable.
