Take the fire department’s advice on chimney repair

October 24, 2010|Handyman on Call, Peter Hotton, Globe Correspondent

Q.We were told by a chimney cleaner (Company A) that though they have been cleaning the chimney every year and we have been using seasoned wood, we have third-stage creosote buildup. Company A completed a cleaning and gave us a quote for installation of a stainless-steel liner. They said they could not clean the creosote buildup, but it didn’t need to be cleaned before installing the liner and they could just install the recommended stainless liner.

Company B agreed that we have third-stage creosote buildup and gave us a quote for a chemical treatment. Company B disagreed with Company A, stating we should clean the flue before installing a stainless liner since the heat can transfer through the liner to the creosote buildup, increasing the chance of a chimney fire.

Company C gave us a quote for a professional deglazing and/or stainless liner. The company stated that all we needed was a more aggressive cleaning with their brushes. They completed the regular cleaning, and stated the flue had creosote buildup. It was thick but not glaze. “We gave very aggressive sweep with coarse brushes . . . and a deglaze is not needed. Recommend having hot fires and burn correctly to minimize creosote buildup. After inspection, stove is ready to use.’’

The fire department advised that we should not install the stainless liner until the deglazing is done due to heat transfer.

Since the flue was cleaned by Company C (which has an A+ rating with the BBB), would it be safe to install a stainless liner and use the wood stove? How seasoned does the wood need to be?

A. Wow, even the Handyman is confused. So, I say go with the outfit that has nothing to sell: The fire department, which knows more about chimneys, flues, liners, creosote, and fires than anyone. It is true that a stainless liner is required with a wood stove, so I would go with Company B. Give wood at least six months to cure.

Q.The metal covers of my bathroom baseboard radiators, are getting pretty rusty. Can I paint them? If so, how?

E.J., Revere

A. To paint, sand off as much rust as possible; for any remaining rust, use Rust Reformer or other brand containing phosphoric acid, which will turn the rust black and make it paintable. Prime with a metal primer and finish with an oil-based paint.

But here is an easier way: buy contact paper, and put it on the metal covers. When it looks kind of tired in maybe a year or so, pull it off and put on a new layer.

Q.I have storm windows (True Channel) that are corroded and the latches simply won’t open. How can I make them work?
