Gutter survey in Underhill, Greater London
Know where you stand with the gutter before you spend money on it. Gutter surveys in Underhill, with photos and a clear written report.
- Gutters that have fallen out of line
- Leaking or loose downpipes
- Water backing up from a hidden gutter
How the survey changes by roof type
Lead-lined valley and parapet gutters
Lead linings are common in valleys and parapet gutters on older houses. A split lining can leak straight into the building.
Cast iron gutters
A cracked cast iron downpipe can leak down the wall unseen, so we check the wall behind for staining.
About our gutter survey in Underhill
Damp on walls, water marks under a valley or streaks down the brickwork can frequently be traced to the gutters. We check whether gutters, outlets or downpipes are the likely source, as far as can be seen safely. If the evidence points elsewhere, like a flashing or the roof covering, we will say so, with a suggested next step. We survey fascias and soffits, parapet and box gutters and eaves gutters, and common reasons people get in touch are rotten fascias or stained soffits and brackets that have dropped or snapped.
Many London terraces have a butterfly roof, with two slopes meeting in a central valley gutter that drains to the rear. From the street you see only a parapet wall, so blocked outlets and split linings go unnoticed until water comes through a ceiling. For a house in Underhill with this kind of roof, the hidden gutter is one of the first things to check.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

What else we do in Underhill
Can I check my roof myself?
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
Leave it or get it looked at?
A blocked valley or parapet gutter does not spill harmlessly. It can back up into the roof space and the rooms below, often in the heaviest rain. It is worth having these gutters looked at before the wetter months. In Underhill, as across London, an overflowing gutter soaks the wall below. A small blockage left for a few winters becomes a damp problem.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. The price is always agreed first.

Common questions in Underhill
Is parking a problem for a survey in Underhill?
London parking needs a little planning, so let us know about permits, bays or a driveway when booking. The visit is then planned around what’s available.
Does a conservation area affect roof work in Underhill?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Is a CCTV drain survey included?
No, CCTV drain work is not part of this survey. The survey covers gutters, outlets, hoppers, downpipes and overflows and flags signs of a drain problem.
Do you carry professional indemnity insurance?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
How much is a gutter survey?
Gutter survey starts from £150, including VAT. The size of the property and the access affect the price. To get a price, call 07833 053749 or email us.

Tips from our surveys
There’s plenty you can do without going near the roof. Here’s what helps most:
- Check for spilling water in a downpour
- Book gutter clearing once a year, more frequently near trees
- Look for downpipes coming loose
- Do not climb a ladder to look in the gutters
If we think the problem lies underground, we’ll say so, so you can arrange a drain survey. We also note anything else we spot on the roof while we are there.
Do not forget valley, parapet and box gutters. They block in the same way as the gutters you can see but you can’t check them from the street, so check they’re included in any clearing work.
What affects the price in Underhill
To price your survey, we check:
- Whether thermal imaging or a drone is needed
- Basic, Standard or Premium
- House, block, shop or office
- How big the roof is
Thermal imaging and drone inspection (where it applies) come with the Premium Survey, from £400 with VAT included. We can help you choose the package that fits what you need to know.
What we need to know
There’s no need for technical words. It’s enough to let us know:
- Your timetable, such as an exchange date
- Any stains, drips or damp patches you’ve seen indoors
- The reason for the survey, such as buying, a leak or storm damage
- The kind of building and roof involved
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply call 07833 053749 or email us whenever suits you.
The survey, step by step
The aim of the visit is simple: to see as much of the gutter as can be seen safely and record it clearly. Notes and photos go into the written report. It typically takes an hour or two at a house, depending on how many gutter runs and downpipes there are. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- First, you tell us what you’ve seen, such as overflows or damp.
- The eaves gutters, downpipes and fascias are checked from ground level and vantage points.
- Any valley, parapet or box gutters are looked at as far as safe access allows.
- We look in the roof space, where there is safe access, for signs of water getting in.
- The findings are written up with photos and recommendations.
Before we arrive
- Leave side gates unlocked
- Have any questions written down, so nothing gets missed
- Find any records of previous roof work
Getting a price
Every survey is priced before it is booked, so you know where you stand. Prices start from £150, including VAT. To book, ring 07833 053749 or send us an email.
Advice
Gutter surveys around Underhill
Outer London has a good many Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Whatever the covering, it’s frequently the fixings, flashings, valleys and gutters that give out first. Wyllyotts Manor, about 3.4 miles north, is one of the historic houses in the wider area around Underhill. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first.
Anyone responsible for a site like St Catherine's RC School will know that a written record of a large roof helps plan work for the holidays rather than in term time. For an older house near a landmark such as St John the Baptist Church, its chimney, valleys and lead work are likely to be the parts that need attention first. If you run a business near Spires Shopping Centre, knowing the roof’s condition lets you budget for work rather than pay for emergencies.
