A good fabricator can hide the seam well.

Once you've managed to spray four of these very light coats over the entire extent of the stain, you can apply polyurethane to the stain and it will not repenetrate, react with the cat urine still in the wood, and cause the stain to appear again.There are other tricks that a flooring professional might use, like ripping up the existing floor in the area of the stain, fabricating a patch out of new oak, and darkening it up a bit with a stain to match the sanded surrounding boards.

Some are complete fabrications just to get your money. 

For me granite runs $38/sq foot but includes fabrication/installation and a new under mount sink.For appliances just do your research.

Other things are: white fabric ductwork tape, vct tiles (9x9), mastic for the tiles, vermiculite insulation to name a few. 

Common Places Mildew thrives on organic materials, such as paper, leather, and many types of fabrics.

I thought Facebook was just a place to go to trash people you didn't like.Anyhow, that ad was a complete fabrication, included a lot of our pictures, inflated the size of the house, and cut the rent.

We are interested to hear if anyone is doing Pre-fabricated homes, NOT MODULE or MOBILE homes. 

I no longer have any good contacts in that world but did know of a small local fabrication shop and called them to ask if they knew anyone that they’d recommend for a little job.

Right now, it seems very cost effective and profitable to do this using a pre-fabricated home... where the materials are cut in a factory, then shipped to the job site, and the home is stick-built on site.
