Gutter sealing in Markyate

Our work covers gutter joints and end caps as well as fascias and soffits plus roofline trims and garage door frames. It’s joint work rather than new guttering. We’re often asked to deal with old sealant on roofline trims that has split and earlier gutter repairs that have peeled off, across roofline trims, gutter end caps and uPVC fascias.

Around Markyate, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

For landlords and businesses

We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.

Markyate questions

Can you do gutter sealing in Markyate?

Yes. We work across London and the South East, and Markyate is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.

Do you work for landlords with property near Luton Airport Parkway station?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.

What sealant do you use?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we are using and why.

Is sealant enough for a gutter that has dropped?

Sealing a sagging joint won’t last. A gutter installer needs to refix it.

Can you seal fascia and soffit joints?

Yes. Our work is the joints, and if a board is damaged, we will tell you.

Do you work on high-level gutters?

That depends on the building. Tell us the height and what’s around the gutter when you ring 0345 464 0079 or drop us an email.

Do you install new fascias or gutters?

Replacement is not our trade. If a gutter is broken or sagging, we will tell you.

How do I get a quote for gutter sealing in Markyate?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.

How it works

Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from an hour or two to a few hours. In a smaller place like Markyate, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  1. We start by tracing the leak and checking the gutter itself is sound.
  2. We clean out the joint and take out the old sealant.
  3. The area is dried so the sealant can bond.
  4. Gutter or exterior sealant is applied and finished.
  5. The run is checked and any debris near the joints is cleared.

Before we arrive

  • For indoor joints, keep the area dry beforehand if you can
  • Keep pets and children clear of the area while we work
  • Let us know about earlier repairs to the joints

Advice

Leave it or put it right?

A dripping gutter joint keeps wetting the same patch of wall. Over time that can stain brickwork, mark render and encourage damp so early sealing is worthwhile. In a smaller place like Markyate, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Take a look at how sealant jobs are priced and our reviews.

DIY versus a professional finish

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Markyate buildings and the weather

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.

Rented homes near Luton Airport Parkway station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. If you live in an older home near Markyate Methodist Church, an extension built onto an older house moves differently, and the joint between them takes the strain. If you look after a building such as Markyate Village School and Nursery, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Keeping the joints in good condition

A little care helps the new joints last. Our advice:

  • Rest ladders on the wall, not the gutter
  • Look for streaks or damp on the wall below gutters
  • Get leaks sealed before the wet months
  • Get a dropping gutter looked at quickly

While checking gutters, glance at the fascia joints too. A small split is quicker to put right.

Rain getting in round a garage door frame can damage what’s stored inside. A reseal sorts it while the frame is sound.
