Power washing – $0.42–$1.40/sq. ft.. You might think you can save some money by power washing the exterior yourself, but homeowners can get a bit trigger-happy with a power washer in their hands. The pressure from the washer can take them unawares, breaking windows, leaking water into window frames and siding joints, and gouging wood. It’s probably wiser to use a hose and scrubbing brush. Rinse off any cleaning solutions thoroughly.
Painting is one of the quickest and easiest ways to give your home's interior a facelift with dramatic results. Fortunately, it doesn't have to be that difficult. Home improvement stores offer samples that you can take home. With these samples, you can try a few colors in large swaths on your wall to see the how the paint interacts with the room's natural light. Compare it against design elements like pillows or furniture to see whether it will work with your overall décor.
Do the cleanup. When the painting is done, send the painter home and do the cleanup work yourself. This will include rolling up drop cloths and collecting scrapings, removing painter's tape (use a hair dryer on low heat to soften the adhesive), cleaning paint brushes, rollers, and other tools, replacing electric switch plates, outlet covers, and light fixtures, and sealing any leftover paint cans and storing them in a dry, temperature-controlled location.
The Coordinator. This person will care for the needs of the rest of the workforce, fetch drinks, make sandwiches, make runs to the store for last-minute needs, cook (or arrange) lunch and dinner, make phone calls, get directions, wash brushes, etc. Don't underestimate the need for this key person! When not gainfully employed, he or she can do some rolling.
Prep work should include removing all loose paint, either with a pressure washer or by scraping; removing any trace of mildew using bleach and water or a commercial solution, and sealing or covering dark stains; caulking all seams, corners and around windows or trim; applying epoxy filler to repair serious woodwork problems; covering dark stains; sanding all rough surfaces, and priming the bare wood with a bonding primer.
You’ll spend between $500 and $3,000 or $1 to $3.50 per square foot to paint concrete. However, expect to pay $2 to $7 per square foot since concrete almost always needs a coat of primer first. Double that price if the concrete requires stripping. Concrete is porous. Sealing it not only helps blend foundations and walls with your home’s aesthetic, but also seals it against water. Repairing or resurfacing concrete costs $300 to $500 for every 100 square feet.
