Gutter sealing in Colney Heath: local notes
Colney Heath is part of Hatfield, one of the post-war new towns. Many homes date from the post-war decades and were built in phases, so neighbouring houses often have rooflines and wall joints of the same age, wearing out at the same time. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Welham Green station? Then leaking gutter joints on a rental are best caught before they stain the walls. If you look after a building such as Colney Heath Junior Mixed Infant and Nursery School, its movement joints, gutters and trims need looking after like any other building’s.
Colney Heath is about 2 miles south-west of Hatfield, in Hertfordshire.

Gutter sealing in Colney Heath, done properly
Gaps along uPVC fascias and soffits look untidy and can let in water and draughts. We seal them in a colour to suit where one is available. We work on soffit joints, roofline trims and gutter end caps, and people most often call us about trim joints where the sealant has failed and drips from gutter joints and end caps.
Outside joints can only be sealed when they’re dry, so work in Colney Heath is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.

The process
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from an hour or two to a few hours. Somewhere as small as Colney Heath, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree which joints need sealing.
- Each joint is cleaned and any old sealant removed.
- The joints are dried.
- The sealant is applied and finished.
- We check our work before we leave.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive

Colney Heath: your questions answered
Is it worth replacing old sealant in an older home in Colney Heath?
In most cases, yes, if it hasn’t been done for a while. Sealant does not last for ever, and its life depends on use, cleaning and weather.
Do you cover smaller places like Colney Heath?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What about gutters on a second or third storey?
Single-storey work is the most straightforward. We will confirm the access for higher gutters once we know more.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Can I add another job to the visit?
Yes. More than one area can be quoted together.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.

Looking after it afterwards
So the new joints stay in good condition:
- Have sagging gutters refixed early
- Look at the gutters while it’s raining
- Get leaks sealed before the wet months
- Clear leaves and moss from the gutters
Have a look at the gutter during a downpour. It’s the easiest time to see a leak.
Split sealant on fascias and trims lets water in behind. Resealing early protects the boards and the wall below.
Do you need gutter sealing in Colney Heath?
Water spilling over a blocked gutter is often mistaken for a leak. If the downpipe is blocked, water has nowhere to go so we check the cause first.
Look out for any of the following:
- Gaps along fascia and soffit joints
- Water dripping where gutter sections meet
- Old gutter sealant that has let go
- Damp patches inside below a leaking gutter
If you live in an older home near Church of St Mark, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- What the quote includes, VAT included or not
- What guarantee comes with the work
- What preparation is included
- Whether all the old sealant comes out first
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
Housing providers, facilities teams and property managers book us too in Colney Heath and across Hertfordshire. We can quote a run of properties together, and we’re fully insured for the work.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
