Around Great Wymondley, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How we quote for gutter sealing
Jobs vary more than people expect. The main factors:
- Working hours on commercial sites
- How much there is to do
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or email us and we will give you an honest view and a quote.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- Whether it’s a home or a business
- Roughly how big the job is
- The problem you’ve noticed
- Any previous sealing or DIY work
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we’ll talk you through the work.
Different surfaces, different methods
Gutter joints
Joints between gutter lengths are the most common leak point. They’re cleaned out, dried and resealed.
Gutter end caps
End caps are resealed where they meet the gutter, after cleaning and drying.
Walls and rooflines in Great Wymondley
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Knebworth House (about 4.9 miles south) nearby, there’s older building stock in the area around Great Wymondley as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
For landlords with property near Hitchin station, leaking gutter joints on a rental are best caught before they stain the walls. For an older house near a landmark such as Church of St Mary the Virgin, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What happens on the day
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. The job usually takes a few hours, depending on the number of joints and the access. Somewhere like Great Wymondley needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we find the drip and check the gutter isn’t cracked or sagging.
- The joint or trim is cleaned out and old sealant removed.
- The joint is dried, because sealant won’t bond to a wet surface.
- Gutter or exterior sealant is applied and finished.
- We check the run and clear any debris we find while we are there.
Preparing for the visit
- Clear items away from the joints we’re working on
- Let us know about earlier repairs to the joints

Advice
Common problems we fix in Great Wymondley
Gutter joints rely on seals that age. Temperature changes make gutters move, and old seals crack or slip.
Keep an eye out for these signs:
- Gaps along fascia and soffit joints
- Dripping gutter ends
- Rain getting in around a garage door
- Cracked sealant along roofline trims
If you look after a building such as Wymondley Junior Mixed and Infant School, its movement joints, gutters and trims need looking after like any other building’s.

- What the cure time is
- Who turns up on the day
Keeping the joints in good condition
So the new joints stay in good condition:
- Clean out the gutters once or twice a year
- Sort out a dripping joint early
- Glance at the soffit joints now and then
- Have sagging gutters refixed early
Have a look at the gutter during a downpour now and then. Drips are easiest to spot while it’s raining.
Once roofline sealant splits, water can get behind it. Resealing early protects the boards.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
