Trusted gutter sealing in Lashenden

Gutter sealing in Lashenden

Garage door frames let rain in when the sealant around them fails. The frame joint is cut out and resealed using a sealant made for outdoor use. Typical jobs include wet patches on the wall under a gutter joint and fascia boards with gaps between them, across garage door frames, uPVC fascias and soffit joints.

Outside joints can only be sealed when they’re dry, so work in Lashenden is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.

There’s a 12-month guarantee on every job, large or small.

When to call us in Lashenden

Sagging sections pull joints apart. Sealing won’t hold if the gutter keeps dropping, so the gutter needs refixing first.

Any of these means the joints need attention:

  • Drips from gutter joints and end caps
  • End caps that drip every time it rains
  • Old gutter sealant that has let go
  • Damp patches inside below a leaking gutter

Around Lashenden, as everywhere, gutter sealing is only as good as the preparation behind it.

Our hiring checklist

How it works

Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes an hour or two for a few joints, longer for a full run. Somewhere as small as Lashenden, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We look at the gutters, fascias and trims and agree the joints to seal.
  2. We clean out each joint.
  3. The joints are dried.
  4. The sealant is applied and finished.
  5. We check our work before we leave.

Before we arrive

  • Mention any tricky access
  • Tell us about any previous sealing or DIY attempts
  • Mention any leaks or damp you’ve noticed

Leave it or put it right?

Leaving a leaking end cap can send water down the wall all winter. Resealing it is a quick job before the damage spreads. In a small place like Lashenden, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Don’t leave a sagging gutter
  • Rest ladders on the wall, not the gutter
  • Keep the gutters clear of debris
  • Watch the wall under the gutters for staining

A sagging gutter needs its brackets checked. Movement will pull the joints open again.

A leaking garage frame lets water reach stored items. Resealing the frame is a quick job while the frame is sound.

DIY sealant or a professional job?

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.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
