I believe there was a thread on this subject previously but I can't locate it. I have some aluminum wiring in my house. Not sure how much but believe it was used in a basement reno years ago. I would like to know if anyone has any aluminum wire replaced and if they have any recommendations for electricians to do the job.

Marty did a great job. Price was reasonable.

I have an older home and it was nothing but aluminum wiring. I had Blair (from GT Smith and Sons) come out and give me a free estimate on having it rewired. Was well worth it!

Aluminum wiring does not have to be removed. You just have to ensure all of your devices (switches & receptacles) are treated with an appropriate marrett. Call Darren @ Nickel Electric for a free estimate & great service.

Copper is the standard these days, but aluminium is still used for very thick service wire because it is much cheaper. Manitoba Hydro uses aluminium all the time. Having said that, aluminium is not ideal and it is more corrosive and so needs to be used with matched (aluminium certified) switches and plugs if it is to remain in your walls. If the place is gutted, then definitely replace the wire with copper. If it means that you are going to have to tear the walls out unnecessarily, then (like the previous poster said) it's probably unnecessary if it is being used properly (loads) and if you have compatible switches and plugs. Noalox compound (an antioxidant) wiped onto any copper-to-aluminium, or aluminium-to-aluminium wire joints is also necessary to preserve the integrity of the aluminium wire. An inspector with Manitoba Hydro may also be a good source to call for information on what you should be doing.

An acquaintance invited to go over to their place and fix things up so their insurance premium would decrease. Of course, they wanted me to do this for free.  
 
They said something about putting in pigtails to the outlets and switches. I declined. I am not an electrician, just a guy who knows what to touch and, certainly, what not to touch.  
 
They need legal paperwork for the insurance company anyway.

If it is just for insurance, I would be asking them exactly what they want. From what I understand, they are often just looking for an electrician to inspect the place and give an assessment on safety and electrical integrity. If the home is old (which if it contains aluminium wire it is reasonably old) that does not mean that it can't pass an insurance inspection. Aluminium is a material that can have POSSIBLE problems if not installed/maintained properly, but by no means does that mean it is unsafe if used properly. Insurance companies are there to provide insurance. I'm confident that they understand that they should not be requiring all homes with aluminium wiring to gut their homes and incur tens of thousands if not hundreds of thousands in renovation costs. They charge a premium based on the risk that is there, and while no material is perfect (copper has it's issues too) the risk is likely still relatively low if it has been inspected by a professional and deemed safe. Nothing in this world is perfectly safe, but then I suppose we would never need insurance then. Consult a professional and get their opinion, and be sure to push for fair answers or get a second opinion if your costs are going to be excessive. Knob and tube wiring, is a completely different story. I know of people that own homes in this city that are over 100 years old, and it is routine that insurance companies will charge a higher fee due to their age, but homeowners are often advised that if an electrician does a thorough inspection and reports it back to their insurance provider, that insurance rates can come down to something more reasonable. Definitely can't hurt, so long as the person doing the work is providing a fair assessment of the electrical system. Even if the insurance company assesses a slightly higher rate for aluminium wire, paying that rate may be much, much less than a complete gut-out over the long term. Make sure your family is safe, and you are good to go.

I have only been here 3 1/2 years, but, this has to be the fire capital of Canada. Electrical fires all over. If there is an unsafe, cheap, way of doing things, it is done here.  
 
In just the last two years I can list off about five fires. In 30 years in a much larger area of Winnipeg, there were three fires. The rate of fires, up here, is very high.  
 
When I was looking at houses, I would see a finished basement and ask "What is behind these walls?" because no-one does anything with a permit, or follows code. The answer was always a shrug.  
 
I am not even looking at it.

Thank you for all of your responses. I think I now know how to handle the situation. I have made sure all the wiring has been done with proper transitions from Aluminum to copper and feel secure. However, I am thinking of selling in the next year or two and have been advised that the fact that the house has aluminum wiring in it may be a problem at time of sale. I therefore am looking into addressing the problem before I actually list the property. Again Thank You for all your advice.

you have a certificate from an electrican that all the lights, switches and plugs were properly transitioned aluminum to copper you should be ok. for selling purposes there is disclosure form you can describe what was done.  
 
there are lots of homes that were built with aluminum back in the late 70s, early 80's and some even later. people are not rewiring the entire home. can you imagine the cost to do a 2 story home. if you can get it done without spending thousands, might be an idea but....  
 
the insurance companies are fine as long as an electrian or hydro signs off on it as being safe.

Your question has transitioned from wiring to real estate. Better to discuss this with a RE agent.  
 
A correctly priced house will always sell.

I bought a house with aluminum wiring. I have had no issues with insurance. Houses have had aluminum wiring for many years.
