What gutter sealing looks like in Warner's End
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Hemel Hempstead, which Warner's End is part of, is one of England’s post-war new towns. Homes here were built in phases, many of them in the post-war decades, so whole streets can have gutters, trims and wall joints reaching the end of their life together.
Homes close to St Alban's Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. If you look after a building such as Micklem Primary School, its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Hemel Hempstead station, leaking gutter joints on a rental are best caught before they stain the walls.

How we handle gutter sealing in Warner's End
A lot of gutter leaks come down to one tired joint. We clean out the joint, dry it and reseal it with a sealant made for guttering. If the gutter itself has failed, we say so. If you are dealing with stop ends leaking at the end of a run and gaps along fascia and soffit joints, we can put it right.
Around Warner's End, garages, outbuildings and extensions all add to the joints on the outside of a home. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Why deal with it now?
Replacing fascias because of open joints is generally unnecessary. A neat seal closes the gaps as long as the boards are in good condition. In an older home around Warner's End, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

What we do, step by step
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. Most jobs take an hour or two for a few joints, longer for a full run. A visit to Warner's End is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at where the water is coming from and check the gutter is not broken or sagging.
- We clean out the joint and take out the old sealant.
- 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’re there.

Questions from Warner's End
Do older homes in Warner's End need their sealant replacing?
Often, yes: cracked, shrunken or mouldy sealant has done its job. The key is cutting all the old sealant out, as new sealant will not bond to it.
Can you help a landlord with a rental near Hemel Hempstead station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses, and we’re fully insured.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
What about gutters on a second or third storey?
It depends on the access. Tell us the height and what’s around the gutter when you call 0345 464 0079 or send us an email.

What we can’t put right
In fairness, there are a few things sealant won’t fix:
- Leaks from the roof rather than a joint
- Rotten or damaged fascia boards
- Water backing up from a blocked pipe
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before you book.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Sort out a dripping joint early
- Keep downpipes clear
- Keep an eye out for wet patches below a joint
- Keep ladders off the guttering
Look at fascia and trim joints when you’re checking the gutters. Splits are easier to seal early.
A leaking garage frame lets water reach stored items. A reseal sorts it while the frame is sound.
