Questions from Appspond
Will you come out to Appspond?
Yes, Appspond is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Appspond in your area for gutter sealing?
Yes. We work across London and the South East, and Appspond is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Do you guarantee gutter sealing?
There’s a 12-month guarantee on every job, gutter and fascia work included.
Is sealing fascia joints something you do?
Yes. Our work is the joints, and if a board is damaged, we will tell you.
Is sealant enough for a gutter that has dropped?
It won’t last. The joint will pull apart, so the fall and brackets need sorting first.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Gutter sealing for homes and businesses in Appspond
Open fascia and soffit joints spoil the roofline and can let weather in. We seal them in a colour to suit where possible. If you are dealing with damp patches inside below a leaking gutter and cracked sealant along roofline trims, we can put it right, on gutter joints, gutter end caps and roofline trims alike.
Around Appspond, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
All our work comes with a 12-month guarantee, wherever you are in Hertfordshire.

Gutter sealing in Appspond: local notes

In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. 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.
High Elms Manor, about 2.5 miles south, is one of the historic houses in the wider area around Appspond, and older homes nearby need a sealant that suits their walls.

Why it’s worth doing now in Appspond

The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
How we quote for gutter sealing
Your quote is based on your job. We take into account:
- How many rooms, windows or areas are involved
- The number and length of the joints
- The type of sealant required
- Whether the work is at height
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
To make quoting easier, let us know:
- If someone has resealed it before
- Where the job is, and your postcode
- If it’s domestic, commercial or a hotel
- A few photos by email, if you can
Every job is quoted individually, so the first step is telling us about yours. Simply phone 0345 464 0079 or drop us an email and describe the job.
How the job changes by surface
Roofline trims
Sealing roofline trims is joint work only. A roofer deals with the roof itself.
uPVC fascias
Our work is the joints, not new fascias. Damaged boards need replacing by an installer.
The process
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from an hour or two to a few hours, and the area is left clean. Somewhere like Appspond needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
Before we arrive
- Mention any tricky access
- Clear items away from the joints we’re working on
- Where the joints are inside, avoid wetting them before we arrive
Ask for a quote
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, call 0345 464 0079 or drop us an email.
Advice
Aftercare tips
A little care helps the new joints last. We recommend:
- Get leaks sealed before the wet months
- Watch for drips in a downpour
- Keep the gutters clear of debris
- Don’t lean ladders against the gutter itself
While checking gutters, glance at the fascia joints too. Splits are easier to seal early.
A drip from a gutter joint won’t stop on its own. Water keeps hitting the same part of the wall and that can cause damp inside.
