What we are called out for in Loudwater

Overflowing gutters can look like leaking joints. A blocked downpipe makes water back up so we check the cause first.

The most common problems we see are:

  • Gaps along fascia and soffit joints
  • Internal damp traced to a gutter joint
  • Drips from gutter joints and end caps
  • Streaks down the brickwork from a leaking joint

Homes close to Christ Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

How to choose a mastic man

Gutter sealing in Loudwater, done properly

It’s easy to live with a dripping gutter joint, but the water lands on the same spot every time it rains. Resealing it is a small job if the gutter is otherwise in good order. Typical jobs include dripping gutter ends and rain getting in around a garage door, on roofline trims, gutter joints and soffit joints.

Outside joints can only be sealed when they’re dry, so work in Loudwater is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.

We stand behind the work with a 12-month guarantee.

Can I do it myself?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

What happens if it’s left?

If the problem is a blocked downpipe, sealing won’t help. We look at what’s really happening and tell you if something else is needed. Around Loudwater, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

What gutter sealing looks like in Loudwater

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Chenies Manor House (about 2.5 miles north-west) are a reminder that the area around Loudwater has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.

If you look after a building such as Christ Church Chorleywood CofE School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Rickmansworth station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Loudwater is about 1 mile north-east of Chorleywood, in Hertfordshire.

Different surfaces, different methods

Garage door frames

Resealing a garage door frame keeps rain and draughts out.

Roofline trims

Roofline trims rely on sealant at their joints. When it splits, water can get behind.

For landlords and businesses

We also work for property managers and facilities teams in Loudwater and across Hertfordshire. We can quote a run of properties together.

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Keeping the joints in good condition

No joint lasts for ever, but care makes a real difference. A few tips:

  • Look at the gutters while it’s raining
  • Glance at the soffit joints now and then
  • Clean out the gutters once or twice a year
  • Check that water runs out of the downpipes

Look at fascia and trim joints when you are checking the gutters. Splits are easier to seal early.

Once roofline sealant splits, water can get behind it. Resealing early protects the boards.

How it works

All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours, depending on the number of joints and the access. Somewhere like Loudwater needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. First, we find the drip and check the gutter isn’t cracked or sagging.
  2. The joint or trim is cleaned out and old sealant removed.
  3. The joint is dried, because sealant will not bond to a wet surface.
  4. An exterior or gutter sealant is applied to the joint.
  5. We look along the gutter and clear debris around the joints.

Getting ready for the visit

  • Keep children and pets away from the work area
  • For business premises, tell us about site rules or sign-in
  • Mention any leaks or damp you’ve noticed
