Plumbing - Check locally for required permits and any zoning law regulations about adding in plumbing, or whenever working with septic and sewer lines. Planning your basement bathroom directly below or close to the pipes of an existing bathroom may help reduce the overall labor and costs. Remember that all drainage lines require a downhill slope to sluice away waste water. If this isn't possible, a sewage injection pump must be installed. An approximate cost of these pumps ranges from $150-$3,000.
So you have decided to turn your musty junk-filled basement into a warm liveable space. Or maybe you are already using the basement but want to style it up a notch. Basement design ideas are limitless. Whether you want a cool chic look or a more dramatic themed basement, the choices are endless. But before you decide on the style you want for your new finished basement, here are a few things to consider.
Sourcing supplies, clearing debris, and doing prep work can all help you save on basement costs. Consider what skills you have and talk with your contractor about what will shave money in each area. You may have the tools and strength to demo walls, which can save you several hundred dollars. Sourcing the materials for the pro takes this task off their labor time and saves you money. Doing prep work and finish work is also a way to cut down on total cost. Painting the walls yourself at the end of the project could save you hundreds of dollars. Negotiate all these aspects before signing your contract.
Of that amount, $15,000 on the labor cost and the rest on material. all walls demolished, cracks in the wall fixed, then insulated and rebuilt, new windows, new electricity wiring, new floor tiling, new web bar, new stairs build from scratch replacing the old. Also, built two closets, one with shelves and the other for clothe-hanging, two utility rooms, one of them where the burner is fire proofed, all walls plastered and painted, wood stained etc. The contractor worked 10 hours a day and finished the entire project in five weeks! (I cooked lunch and provided cold drinks.) could have build a bathroom for $3000, but I decided to do that another time.
Sometimes a finished basement floor makes the bottom stair a little too shallow, throwing off the whole run. Tom Silva's fix: Measure the rise of each step. If any are shorter than 7 inches, you can remove the treads and add spacers to pad them out as you go up. Just keep heights below code maximum, and make sure they don't differ in height by more than ⅜ inch.
Remodeling a finished basement is costlier. The demo can cost from $1,500 to around $3,000 to prep the site. System upgrades include expanding the HVAC and electrical, but even if you already have a bathroom in place, remodeling can add $1,000 to $4,000. Finally, the finishing work can be kept low if you stay with the basics, but upgrades to hardwood floors and other luxuries will add $7,000 to $10,000 to the job. On average, expect to pay $13,200 to $30,500 for this job.
Unless you install a plywood subfloor, your basement floor is likely to be a concrete slab. Fortunately, concrete accepts most common flooring choices, from paint to vinyl, laminate, tile, and carpet. Most solid wood flooring is not recommended for below-grade installations, however, because it shrinks and expands, resulting in gaps or warping. Engineered wood is a good alternative because it shrinks and expands a little less.
Before walls and flooring can be added, the basement must first be professionally framed. Framing an unfinished basement can be very expensive; not only will it require a large amount of labor, but material costs are high as well. If you consider all the lumber your contractor will need to lay, plus crossbeams and studs, you will find that lumber is going to be one of the costlier aspects of the project.
