Gutter sealing in Royal Docks, done properly

Many dripping gutters are just a failed joint or end cap. We clean out the joint, dry it and reseal it using a gutter sealant. If the gutter itself has failed, we say so. We’re often asked to deal with wet patches on the wall under a gutter joint and rain getting in around a garage door, on soffit joints, gutter joints and garage door frames.

Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall.

Big or small, you get the same 12-month guarantee.

What gutter sealing looks like in Royal Docks

With historic houses such as Queen's House (about 2.7 miles south-west) nearby, there’s older building stock in the area around Royal Docks as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts.

If you live in an older home near Church of the Ascension, an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Custom House station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Why it’s worth doing now in Royal Docks

Sealant will not clear a blocked downpipe. We look at what’s really happening and point you to the right trade if needed. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.

Your questions about gutter sealing in Royal Docks

Can you help a landlord with a rental near Custom House station?

Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.

Is parking a problem for a job in Royal Docks?

Parking in Royal Docks, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.

Can you quote for more than one area?

Yes, and it often makes sense. Combining jobs makes good use of the visit.

Should I try DIY first?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.

Where are you based?

Mr Mastic is based in Crawley. Our applicators cover Royal Docks.

Is it messy?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

Do you do commercial work?

Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.

Do you replace gutters or fascias?

We don’t replace gutters or fascias. We will tell you if the gutter needs replacing so you can call the right trade.

How it works

Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours, depending on the number of joints and the access. In a London area like Royal Docks, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.

  1. First we trace the drip and check the gutter isn’t damaged.
  2. We remove the old sealant and clean the joint.
  3. We dry the joint so the new sealant can bond.
  4. A gutter sealant is applied to the joint.
  5. We check the run and clear debris near the joints.

Preparing for the visit

  • Mention any leaks or damp you’ve noticed
  • Mention any tricky access
  • Tell us if parking is tricky

How to get a quote

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, call 0345 464 0079 or send us an email.

Related advice

Can I do it myself?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

If you’ve already had a go yourself, that’s fine. We cut it out and start again.

What we’re called out for in Royal Docks

When a gutter sags, its joints open. Sealing will not hold if the gutter keeps dropping so the brackets need attention first.

Any of these means the joints need attention:

  • Drips from gutter joints and end caps
  • Old gutter sealant that has let go
  • Old sealant on roofline trims that has split
  • Gaps along fascia and soffit joints

As a London address, Royal Docks can be tricky for parking: let us know about parking bays, permits or a driveway.

What to look for in a quote

  • How long to leave it before use
  • How much experience the applicator has
  • Which sealant they’ll use, and why
  • Is the old sealant removed completely?

How to choose a mastic man

For landlords and businesses

From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.

Looking after it afterwards

To keep the joints looking good and working properly:

  • Check fascia and soffit joints for gaps
  • Check that water runs out of the downpipes
  • Clean out the gutters once or twice a year
  • Keep an eye out for wet patches below a joint

A sagging gutter needs its brackets checked. If it drops, the joints will open.

The sooner a gutter leak is sealed, the less water reaches the wall. If we find a bigger problem, we will tell you.

When something else is needed

Before you book, it’s worth knowing the limits:

  • Boards that have decayed or split
  • Roof leaks, slipped tiles or failed flashing (a roofer’s job)
  • Guttering that needs replacing

If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before you book.
