Hello,
We are about to start renovating the basement and have quite a few pipes that we would like to conceal. Most of the pipes are insulated with asbestos.
Do you have any tips on what we should do, should we first remove the stuff or is it okay to just enclose the pipes with MDF boards and some inspection hatches?

Please share your experiences 🙂
 
  • Pipes with insulation near a window in a basement, some covered with a material resembling asbestos, part of a renovation project.
  • Pipes in a basement ceiling, some covered with insulation, near a window with blue plastic outside; renovation context with asbestos concern.
  • Old pipes with insulation running along a basement ceiling, some covered with possible asbestos, with visible damage and a nearby window.
  • Pipes insulated with asbestos in a basement, positioned near a small window. The surrounding walls are unpainted, and a door is open.
  • Basement corner with exposed pipes, some insulated, a tiled wall, a radiator, and a sink.
  • Pipes in a basement, some insulated with worn materials possibly containing asbestos, highlighted against a blue floor and white walls.
  • Damaged insulated pipes in a basement corner, with some insulation missing and cracks visible.
  • Insulated pipes in a basement ceiling, possibly containing asbestos, with nearby wood planks and a white panel.
  • Basement corner showing exposed pipes, some covered with insulation, and a wall with visible wear.
  • Basement pipes, some insulated with asbestos, near a small window; shows plumbing setup in a renovation project context.
  • Pipes in a basement with some insulated with foam and potential asbestos concerns, alongside exposed walls showing damage and fittings.
I mostly see styrofoam, glass wool, and stone wool in those pictures. Possibly there's asbestos in a pipe bend in the sixth image.

Pipe bends, branches, and similar used to be insulated with a form of "asbestos powder" which was often orange in color. The straight pipes used to, like now, be insulated with pipe sleeves made of stone wool or glass wool. A pipe sleeve is thus a preformed tube of insulation that's slit so it can be fitted onto the pipe. Today there are special pipe sleeves for bends, etc., or you have to cut and miter pipe sleeves, but in the past, it was done simply by filling with loose insulation powder in the form of asbestos where straight pipe sleeves couldn't be used.

Since it is powder, there's no really good way to remove asbestos from pipes without dedicated equipment. It will create dust. You don’t want that dust in your regular vacuum cleaner.

Call a restoration company, and they'll fix it in an afternoon, and safely. They can also easily distinguish between the different types of insulation.

The alternative is to do nothing and encapsulate it. But now the insulation is already so damaged (both the potentially asbestos-containing and all other insulation) that it's best to replace it. It's not for fun that pipes are insulated, but to avoid energy losses from hot pipes and condensation on cold pipes.

Is it tested or are you guessing?

Pipe bends, branches, and similar parts were often insulated with a form of "asbestos powder" which was often orange in color. The straight pipes used to be and still are insulated with pipe sections made of stone wool or glass wool. A pipe section is a pre-formed tube of insulation that is split so it can be placed over the pipe. Today, there are special pipe sections for bends, etc., or you have to cut and miter pipe sections, but in the past, it was simpler to fill in with loose insulating powder in the form of asbestos where straight pipe sections couldn't be used.

Since it's powder, there is no good way to remove asbestos from pipes without proper equipment. It will create dust. You don't want that dust in your regular vacuum cleaner.

Call a remediation company, and they'll handle it in an afternoon, safely. They can also easily distinguish between different types of insulation.

The alternative is to do nothing at all and build it in. But now the insulation is already so damaged (both the one that possibly contains asbestos and all other insulation) that it's best to replace it. Pipes are insulated for a reason, to avoid energy losses from hot pipes and condensation on cold pipes.
Okay, so you're recommending that we start by cleaning out all the old insulation via a remediation company and then add new insulation.

We sent tests from two different pipes in the basement and one of them was asbestos.

In my world, it looks like mineral wool with gauze and plaster.

Put on a good mask and the Mumin painting suit and carefully cut away the insulation. Pack it into bags directly. Sweep and wet mop thoroughly afterwards, done! A company is likely to charge quite a bit due to people's fear.

We sent samples from two different pipes. The one I have marked in green is with asbestos and the one I have marked in red is without asbestos.
 
  • Pipes in a utility space, one highlighted with a green circle indicating the presence of asbestos material.
  • Pipes in a basement ceiling; one pipe is marked with a red circle indicating it is without asbestos, as mentioned in the discussion.

"Mumin-målardräkten"
The most important new word of the year! 😃❤️

I actually don't want to do anything about the mess, just want to hide all the pipes. Can I tape the mess with duct tape before boxing them in with MDF boards?
 
Just my perception. It looks quite messy and perhaps a cleanup of the pipework would be good. Now they are there, and either you paint the pipe insulation with a plastic paint or just enclose them. The latter would involve a lot of construction and result in low ceilings in some places.

Okay, I'd like to know more about the plastic paint you mention here. Does the paint hold in all the dust that might be released from areas where the pipe insulation is damaged? What do you think about duct tape?
 
One way to encapsulate the asbestos is to wrap them with a layer of fabric. Take old sheets that you tear into 1 dm wide strips, attach them with ample wallpaper paste, wrap them around the pipes in a spiral (I think you get it), make sure they overlap. When the paste has dried, you can paint a layer with the cheapest ceiling paint. Done!
 
NJA silvertape. It's a bit tricky to apply. Better then to wrap with regular thicker gauze and paint on it, as it's gauze that is placed on the outside of any asbestos and then only in the curves. The straight sections have fiber insulation under paper and gauze.
