If you are putting down vinyl flooring the old floor must be perfectly smooth or every little dimple will telegraph through the new floor over time. In your case Luan should be screwed down and every seam and screw head be filled/smoothed with the cement compound recommended for that purpose.

You don't necessarily have to go back and level if you use a water level and make sure all the tops of the piers are at the same height when done. What happens is the frame may get slightly twisted when the home settles crooked. When you jack it level at some piers the frame does not settle back dow...

The last home I leveled was 12" low on the back half at one corner. They propped doors open inside with rocks. Once finished leveling it took 6 months for the frame to settle down on some piers due to the twist in the frame.. As far as buying a proper jack for $20 I consider that a expense well...

No. The vinyl siding is not a air barrier. There is more than enough air circulation but water will also get behind the siding so make sure you use a properly installed and taped house wrap.

Venting will not prolong the life of the OSB. It will rot first closest to the ground due to rain splashing against it. Make sure you get a good quality paint applied to both the inside and outside, hopefully seal the bottom edge, of the skirting and the life of the skirting will be extended conside...

No venting is required as the siding is not sealed from air infiltration. It is advisable when strapping to add rigid foam insulation between the strapping and house wrap before siding. The insulation adds support to the back of the siding and help insulate as well. I would also strongly advise usin...

Are you renting a lot in a park. If so you may want to check with management regarding the skirting material before you invest any time and effort in venting. If the park rules do not allow OSB for skirting you may end up having to remove it and install vinyl. One thing park owners usually hate is r...

As Greg has stated it is possible to paint vinyl but it must be properly prepared and is labour intensive. It is not advisable to change the colour as the paint will deteriorate, peal and chip over time exposing the white and creating a eye sore (in my opinion). Cost wise, if the siding you want to ...

If you are purchasing used price and availability will dictate what you have to chose from. The majority of recent (past 10 years) manufactured homes are of similar assembly and material none of which are that great but far better than in the past. Find the one you like, inspect it thoroughly to det...

Having completed 3 total home renos in the past two years, including all drywall, I would recommend you put up all your drywall in the home and then hire a professional taper to complete the work. The tape/mud job to do a complete home should only take about three days and ultimately will save you b...

To level your own home all you need is a water level, a 20 ton hydraulic jack and the inclination to do it yourself.
You can find instructions on the Internet to make your own level.

The choice of door material should only matter to you. Any door can be cut to fit assuming you have the proper tools. A metal cutting blade in a circular saw is preferred for metal doors however a regular carbide tipped blade will work. Buy a cheap 7 1/2" construction grade carbide tip blade an...

The straight answer to your question is they are both correct. A roof over is acceptable assuming only one existing layer is in place. The better way is to remove the old shingles and put down new. As with everything in life you can have cheap or you can have quality but you can not have both. As th...

As a amature having to do drywall in the past my preference would be 4 X 9 sheets (best option) installed vertically and have only factory tapered edges to mud.

Home Depot sells the corrugated roofing metal in a rainbow of colours including white.
The galvanised reminds me of something from the POW camps in 2nd world war movies. The small isolation boxes. Not particularly an attractive image.
