Leaking Silicone Sealant - A Cultural Problem

One of the most common jobs our London handymen undertake is the resealing of baths and shower cubicles. People sometimes just want the old sealant replaced because it has become discoloured or mouldy, but mostly it is because signs of a leak have appeared on the ceiling below the bath or shower.

It must be said, it is not always the silicone, in some cases there are cracks in the grout or water is making its way behind a valve or tap. However nine times out of ten there is a gap or hole in the sealant. The cure is often simple, scrape out all the old silicone and replace it.

Leaking sealant is a very common problem in the UK. If you visit your local B&Q or Homebase you'll find a whole aisle dedicated to different kinds of sealants, sealing strips and sealing tapes. All offering new and improved ways to seal your bath or shower. But why are there so many baths and showers that leak, is it the sealant?

I spent the first 24 years of my life in South Africa and I had never seen a tube of silicone, a silicone gun or heard anyone complain about a leak due to a hole in their bath or shower sealant until I moved to London. I realise now when I go back to South Africa on holiday that all baths and showers are sealed with silicone exactly the same way they are in the UK. So why is leaking silicone sealant such a problem here and not in South Africa.

As with most blog articles, I pose the question just so I can answer it myself. So here goes.

I believe the answer lies in space, or lack there of. The UK, or London in particular, has a lack of space. Houses are split into halves, quarters, basements and lofts. Flats are shared, even rooms are shared. Everybody lives either on top of or underneath someone else.

If you have ever lived in a flat or house share you will know that the efficient scheduling of shower/bathroom facilities is the cornerstone of any successful house share. The shower is in almost constant use. Some flatmates shower in the morning, some in the evening, some in the morning and evening. My point is the average London shower cubicle sees a lot of action and a lot of water. If there is even the slightest hole in the silicone with a constant stream of water flowing over it day in day out. Of course there is going to be a problem.

I propose that even the best silicone job is susceptible to wear and tear and a shower or bath that sees constant use day in day out will need to be resealed every couple of years to ensure a permanent and good seal.

Good Neighbours

One of the jobs we are doing today has an interesting story behind it that I thought I would blog about.

We took a call last week from a gentleman who wanted to know what the cost and availability was for Silver Saints to supply and fit a replacement front door. He attached a photo of the current door and wanted a like for like replacement. After a bit of research we found the same door was available from Wicks in SW19. Having given him a fixed price for the supply, delivery and fitment of the new door. He agreed to go ahead with the work and asked us to contact someone else to gain access to the property as the person who lived at the address where the door was to be fitted was in hospital.

It turns out that the door had been kicked in by paramedics who needed to gain access to the property because the elderly gentleman that lived there had fallen ill and was unable to let them in.

The gentleman who had contacted us was one of his neighbours who had volunteered to arrange and pay for the replacement of the door and the person who was going to give us access to the property was yet another neighbour. They wanted to ensure that the property was secure and that the elderly resident would not have to worry about having the door replaced when he returned from hospital later in the week

Its good to know that people still go out of their way to help each other out and that a sense of community still exists within a very complex city like London.

My Day Out with the Ladder.

In case you don't know, all our handymen travel around London on either motorbikes or push bikes. One of the few drawbacks of these modes of transport is that we cannot carry step-ladders with us. This is not normally a problem as most customers have a step ladder or sturdy chair we can stand on if a bit of extra height is required.

This however was not the case for one of our customers who had just moved in to a flat in W2. Unfortunately she did not have a step ladder or much furniture yet and wanted us to install some curtain rails and replace a faulty lighting transformer.

So yesterday morning I set out from SW12 on my push bike with a trailer loaded with a 4 rung folding step ladder. Traveling through Clapham Common, over Chelsea bridge and across Hyde Park I arrived at the customers house at 9am as the Handyman Nick was just arriving.

I spent the day following Nick from job to job and even assisted in assembling some furniture at his last job of the day. After which I headed home, following the same route back through Hyde Park.

All in it was a 2 hour round trip and about 2000 calories of energy to get the ladder to W2. But I loved it.

YouTube

We have recently set up a Silver Saints Youtube chanel which will feature how 2 videos of our london handymen carrying out some of the more common jobs we take on.

We have posted our first video on how to hang a flat screen TV and aim to post a new video each week. Look out for next weeks video on changing sash cords.

Last Minute Cancellations

We have a fairly liberal cancellation policy. A customer can cancel their job at anytime before we actually turn up at the door without attracting a charge. Although we do get last minute cancellations and they are always disappointing, the fact that our average job is only 90 minutes long, means that it normally is not the end of the world. We can usually reshuffle our schedule in order to keep the handyman busy.

But yesterday we had a customer cancel a large wall-papering job, that was due to last two days, the evening before the work was due to commence. It was too late in the day for us to do anything about the handyman's schedule and as a consequence he had a very unproductive day.

We have always shied away from jobs lasting more than four hours, mainly because they are normally complex, hard to be competitive on pricing and are generally a greater credit risk. This particular customer was desperate to get the work done and had already given us credit card details for payment so we were happy to take on the work. But in the end we had our figures burnt and it has given us yet another reason to stick to the small jobs that we do so well.

Tap Repairs, Tap Valves and Tap Spares

One of the jobs we have become experts on over the years is curing problems with household taps. Identifying makes and models from emailed photos, sourcing specific valves, ceramic cartridges, handles, diverters and indices has become somewhat of an obsession amongst the Silver Saints Operations Team.

I had a particularly satisfying enquiry this morning. A lady had picked up one of our business cards at her local South West London coffee shop and given us a call about her leaking bath taps. She obviously did have some DIY knowledge as she explained that the tap internals would need to be changed as the problem with the valve felt a little more than just a worn washer.

I asked her to email me a picture of the taps. Which she did.

Within a half-hour we had identified the make and model of the taps and ordered the replacement parts. I'd be very surprised if any other London handyman service or Plumbing service had the same knowledge or resources to identify and source parts from a picture of a 10-15 year old bath tap. But we do it half a dozen times a week.

It must be said, we don't always find the parts needed. Sometimes we just don't have enough clues from the taps themselves to identify the manufacturers and sometimes they are just cheap no-name taps imported from China and sold online (so parts are not available). But at least a customer can be confident that if we suggest fitting a new tap, the parts really are impossible to find.

Upgrading Electric Showers

Many Londoners have a love hate relationship with electric showers. Landlords and property developers love them, because the allow an additional shower at relatively low cost. While tenants hate them, because of their mediocre performance (especially in Winter).

Electric showers are fed cold water directly from the mains. The shower then 'instantaneously' heats the the incoming water to the desired temperature set by the user. In fact what is happening is the shower slows the flow of water down to give it enough time to heat the cold water. That is why in winter, when the incoming mains water is very cold, all you get is a trickle from the shower head.

The more powerful the rating of the shower (7.5Kw, 8.5 Kw, 9.5Kw or 10.5 Kw) the quicker it can heat up the water and the less it has to slow the flow down.

A lot of people have picked up on this fact and have opted to upgrade their poorly performing 7.5KW showers with a more powerful 10.5KW shower. Unfortunately, DIYers don't always understand the electrical implications of changing the rating of an electrical appliance to the rest of their wiring and protective devices (fuses, miniature circuit breakers). Simply, the amount of current that a cable can carry without overheating is limited mainly by the cross sectional area of the cable. Fuses and MCB are in place to protect the cable from overheating and therefore are rated to blow or trip before the electrical current gets to the cables failure current.

A 7,5 KW shower will draw a maximum current of 30Amps - 32 Amps. An installer would thus get away with a using a 32amp MCB and a 6 mm2 cable. A 10.5Kw shower would draw a maximum of 40-43 Amps and therefore would require a cable thickness of at least 10 mm2 which should be protected by a 45amp MCB. So if a person wishes to install a 10.5KW shower in place of a 7.5KW shower they should be confident that the electrical supply is capable of coping with such a change.

With a bit of domestic electrical knowledge and plumbing knowledge, upgrading an electric shower is a straight forward job. But without knowing what one is doing it can lead to a dangerous situation, mainly a fire risk.

So my advice is if you are adamant on doing the work yourself, get a competent person to check your electrics for you. Otherwise hire a professional handyman to do the whole install for you.
