Hi all, I need to replace the roof on my garage (7m x 3m). It used to be corrugated asbestos cement, however it needed removing because it was in deteriorating condition. I have access to OSB3 board and plan on boarding it. However, i'm a bit stuck when it comes to the actual roof...

Hi all, I've currently got an issue with my front door and wondering if anyone would be able to provide advice. The door doesn't seal properly when closed, and there is a very small gap. The door needs to be moved "inwards" further into the frame. After some searching around online, it...

Hi all, Had a new condensing boiler put in my loft (to replace my old combi boiler). Needed a condensate drain connecting. The installer attached 22mm overflow pipe to the boiler. This pipe then goes into 32mm pipe which runs outside. As far as I understand, this is correct to use 32mm...

Hi all, I'm after a bit of advice. I recently had to drain the central heating system due to doing something very stupid (put a screw through a CH pipe, feel like a right wally). Anyway, the pipe has now been fixed, and the system has been filled up manually using the filling loop...

Hi all, Wasn't sure where to post this, hopefully this will be the right place. I have recently had mould growing in the house, so decided to look into ventilation. The house is sealed up quite tight (double glazing, cavity insulation etc) so I figured there is nowhere for stale air to go...

Hi all, I have a rather large garage (7m x 3m) which had an old leaky corrugated asbestos cement roof. The asbestos roof has now been fully removed. I plan on installing a new roof myself (with my Dad who is a bricklayer), but thought I'd come and ask you guys for advice. I'm thinking...

Hi all, Wondering if anyone could help me with the following problem? Basically, I have a speaker in a bellbox which "turns on" when the "trigger line" is reduced to 0v. While the trigger is above 4v, the speaker stays quiet. The line is usually at 12v, until I want to make a noise...

Hi all, I'm currently setting up a house alarm system. I have an external bellbox that requires 12 volts DC to "trigger" it's speaker. However, my alarm control panel outputs 8.5 volts as it's trigger output. I have attempted to use a 12v relay, but the 8.5v is not enough to trigger it...

Hi all, I have a bellbox on the side of my house that the previous owner left, and would like to try it out to see if it works. I've opened the bellbox up, it is an Everspring s120 1aa - can't find any information online about this model, but the manufacturer's website is...

Hi all, I've recently acquired an alarm control panel with some PIR sensors, but I don't have a bellbox. The control panel manual (which I downloaded off the internet) is not very useful. Basically, I need to purchase a (hopefully cheap) bellbox. The control panel has two wires for...

Hi all, Wondering if anyone could help me with the following problem: In certain areas on our walls, there is (what seems to be) a concrete internal render on the walls which is crumbling. These patches seem to occur on a random basis (on any outside wall; front, back, and side of the...

Hi all, I've been looking to purchase a new alarm system. Ebay seems to have some really good looking systems with loads of features at a cheap price, probably shipped straight out of China. One example: http://cgi.ebay.co.uk/Wireless-Autodial-Home-Burglar-Alarm-System-08B-/250587476616...

Hi all, I'm currently looking into purchasing an alarm system (nothing too fancy, just a couple of PIRs) to protect the home. Been looking around (mostly on ebay) for a system to setup myself, and noticed that the majority of alarm systems are wireless. Wireless would be a great option...

Hi all, We have a cavity wall, where the outside is clay bricks and the inside is concrete blocks. However, in some places (seemingly randomly throughout all 3 outside walls), the concrete blocks have "dents" in them. When placing a finger in a "dent", the block begins to crumble and the...

Hi all, We recently had a company around to provide cavity wall and loft insulation. After they had left, we noticed that they had left holes in the outside brickwork, without pointing them up. You can see all the "foam" inside the cavity. No one mentioned anything to us about leaving...
