Landlords, agents and businesses in Whiteley

In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

Gutter sealing in Whiteley

For gutter sealant to hold, the joint has to be clean and dry. So the old sealant and grime come out first and the joint is dried before the new sealant goes in. If you are dealing with leaking gutter joints and stop ends and stop ends leaking at the end of a run, we can help, whatever the surface.

Homes around Whiteley range from older cottages to newer houses, with walls and rooflines of every type. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.

Whatever the size of the job, it’s backed by our one-year guarantee.

Looking after it afterwards

Good habits help new joints last longer. A few tips:

  • Rest ladders on the wall, not the gutter
  • Sort out a dripping joint early
  • Make sure downpipes are not blocked
  • Look at the gutters while it’s raining

Make sure downpipes are not blocked so the gutter can drain. A blocked pipe backs water up to the joints.

A drip from a gutter joint won’t stop on its own. The same spot gets soaked every time it rains, which can lead to staining and damp.

How the job changes by surface

Garage door frames

Frame-to-brick joints face the weather. We use a sealant made for outdoor joints.

Roofline trims

Trims along the roofline are often finished with sealant. When it splits, water can get behind.

What we are called out for in Whiteley

Roofline sealant ages in sun and rain. It hardens, shrinks and splits after some years.

People usually contact us when they notice one of these:

  • Earlier gutter repairs that have peeled off
  • Trim joints where the sealant has failed
  • Water running down the wall below the gutter
  • Fascia boards with gaps between them

If you look after a building such as Whiteley Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

10 questions to ask before booking

What gutter sealing looks like in Whiteley

Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

For an older house near a landmark such as St Margaret Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move. For landlords with property near Swanwick station, leaking gutter joints on a rental are best caught before they stain the walls.

How the visit works

Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours, depending on the number of joints and the access. Parking around Whiteley is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  1. We look at where the water is coming from and check the gutter isn’t broken or sagging.
  2. Old sealant and dirt are removed from the joint.
  3. The area is dried so the sealant can bond.
  4. An exterior or gutter sealant is applied to the joint.
  5. The run is checked and any debris near the joints is cleared.

Getting ready for the visit

  • Mention any leaks or damp you’ve noticed
  • On commercial sites, let us know about site rules
  • Where the joints are inside, avoid wetting them before we arrive

  • A gutter length that has split
  • Brackets that have snapped or loosened

Whiteley questions

Do you cover Whiteley for gutter sealing?

Yes, Whiteley is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing.

I let a flat near Swanwick station. Can you help?

Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.

Can new sealant go over the old?

No, it will not last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.

Where are you based?

Can you quote for more than one area?

Yes. Just list everything you need and you’ll get one quote.

Is there any odour?

Some sealants have a smell while they cure, but it fades. Opening a window helps.

What should I tell you?

A short description and the location, with pictures by email if possible. If we need more, we’ll ask.

Is gutter cleaning part of the job?

We clean the joints we are sealing and any debris nearby is cleared. A full gutter clean is a separate service.
