Landlords, agents and businesses in Northaw Valley
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
We work for landlords and letting agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
Gutter sealing for homes and businesses in Northaw Valley
Open fascia and soffit joints spoil the roofline and can let weather in. They’re sealed in a matching colour where possible. We are often asked to deal with rain getting in around a garage door and end caps that drip every time it rains, across gutter joints, garage door frames and roofline trims.
Older homes in small places like Northaw Valley may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
Every job is covered by a 12-month guarantee.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep an eye out for wet patches below a joint
- Check fascia and soffit joints for gaps
- Make sure downpipes aren’t blocked
- Sort out a dripping joint early
A sagging gutter needs its brackets checked. Movement will pull the joints open again.
Leaking gutter joints get worse over time. Water keeps hitting the same part of the wall, which can lead to staining and damp.
When to call us in Northaw Valley
Sagging sections pull joints apart. Sealing will not hold if the gutter keeps dropping so the brackets need attention first.
Signs it’s time to call us include:
- Gaps along fascia and soffit joints
- Quick sealant fixes on gutters that didn’t last
- Old sealant on roofline trims that has split
- Damp on an inside wall under a dripping gutter
If you let a flat or house near Crews Hill station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Yes, Northaw Valley is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Will sealant fix a dripping gutter joint?
In many cases, yes. Cleaning, drying and resealing the joint normally works. If the section is split or warped, it needs replacing.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
Can you fit new guttering?
No. We seal leaking joints, end caps and trims. A gutter installer or roofer deals with replacement.
Do you work for landlords and businesses?
Yes. We work for householders, landlords, letting agents, businesses and hotels.
Is sealant enough for a gutter that has dropped?
Not on its own. A sagging gutter pulls its joints apart so it needs refixing before sealing.

What gutter sealing looks like in Northaw Valley
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. With historic houses such as Wyllyotts Manor (about 2.4 miles west) nearby, there’s older building stock in the area around Northaw Valley as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Homes close to Parish Church of St Thomas A Becket include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. Managing a site like St. John's Senior School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

uPVC fascias

Why act early in Northaw Valley
Sealant will not clear a blocked downpipe. We look at what’s really happening and tell you if something else is needed. Around Northaw Valley, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
