Gutter surveys for homes and businesses in Harmondsworth
Owners get in touch after seeing an overflow, finding damp or planning ahead for winter. Landlords and managing agents use the report to plan upkeep, and some buyers want the rainwater system checked before exchange. The survey and report follow the same steps whatever the reason with photos and clear recommendations. We survey on weekdays and at weekends. We survey fascias and soffits, valley gutters and outlets and hoppers, and common reasons people get in touch are leaking or loose downpipes and overflowing valley or parapet gutters.
Victorian and Edwardian terraces are found right across London, many with Welsh slate roofs, shared chimney stacks and parapet or valley gutters. Good slates can last over a hundred years, yet the nails often give out first and let slates slip. In Harmondsworth, as across London, that is why a roof needs a careful look rather than a glance from the street. Lead flashings and shared chimney stacks on these houses need a close look too.
What you get is a clear record of the gutter on the day we saw it. That makes it useful now and a handy reference later.

Useful tips for Harmondsworth property owners
You don’t need to be a roofer to help. Here’s what helps most:
- Include valley, parapet and box gutters when clearing
- Get the gutters cleaned out every year
- Look out for overflows when it pours
- Look for new stains on ceilings below valleys after rain
Landlords and managing agents can keep the report with the building’s records and use it to plan upkeep. Photos make it easier to explain the work to owners, tenants or contractors.
Have your gutters cleared at least once a year or more frequently near trees. The best time is usually after the leaves have dropped. Clear gutters can carry water away as they should.

Harmondsworth: your questions answered
Can parking be tricky for a visit in Harmondsworth?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Does a conservation area affect roof work in Harmondsworth?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Can you inspect my roof with a drone?
Yes, where applicable and safe. 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.
Are you structural engineers?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
Could my damp wall be caused by the gutters?
Leaking gutters and downpipes are a common cause of damp walls, and the survey looks for that. If the cause looks like something else, the report says so, based on what we can see.
Are you insured?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
How do I arrange a gutter survey in Harmondsworth?
It’s easiest to ring 07833 053749 or email us. Give us the address and a few details about the roof. Surveys run on weekdays and at weekends.
Local roofs in Harmondsworth
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Whichever you have, the details that tend to fail before the covering itself get the closest look. What can be done to an older roof may depend on listing or a conservation area. The council is the place to check, along with Historic England’s list, ideally before any re-roofing is planned.
As a London address, Harmondsworth can be tricky for parking: tell us about permits, visitor bays or off-street space when booking, as a space near the door can’t be promised. For landlords with property near Heathrow Terminal 5 Rail station, a roof report helps you deal with small faults before they turn into a call from a tenant. Anyone responsible for a site like Harmondsworth Primary School will know that large buildings have long gutter runs and big roofs that need checking like any other.

What we look at
- Eaves gutters
- Fascias and soffits
- Valley gutters
- Downpipes
- Parapet and box gutters
- Outlets and hoppers
How the survey works
Before we start, let us know why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. The visit typically takes between one and two hours for most homes, and longer where there are parapet, valley or box gutters to follow. In a London conversion, the way into the loft space is often from a communal landing or the top flat. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Otherwise, the visit in Harmondsworth runs like any other.
- We ask about overflows, damp or leaks you’ve noticed.
- Gutters, downpipes, fascias and soffits are inspected from safe vantage points.
- We check hidden gutters, such as valleys and parapets, where it is safe to see them.
- Where the loft can be reached safely, we check it for staining or damp.
- You get a report with photographs and recommendations.
Preparing for the visit
- Keep pets inside or away from the areas we’re looking at
- Jot down any questions you want answered
- If you’re buying, let the agent know when we are coming

Related advice
Leave it or get it looked at?
Overflowing water soaks the walls under the gutter. Given time, it can cause damp patches, damaged pointing and rot in nearby timber. Spotting the problem early tends to mean a simpler fix. In a London terrace or conversion, a roof defect rarely stays your problem alone: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Finding it early keeps the work smaller.

Read how roof surveys are priced and what we found on two real jobs.
What a survey costs
Prices vary from roof to roof, for these reasons:
- The package you choose: Basic, Standard or Premium
- How big the roof is
- Extra roofs, like extensions, dormers or garages
- House, block, shop or office
Our price is from £150, including VAT. The final price depends on the size and height of the roof, how it can be seen safely and the package you choose.
Getting in touch
You don’t need to know any roofing terms. Just let us know:
- Pictures from the garden or a window, if you have them
- Where the property is, with the postcode
- What’s prompted the survey
- Where water is showing inside, if it is
If you’re buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just phone 07833 053749 or drop us an email when you’re ready.
Should I look at the roof myself first?
Your own check is a good start, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level.
It is useful to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking, as it helps us focus the survey.
