"I just had Elm Construction Services replace the roof on our new home. I have to say, I’m really impressed. We went with asphalt shingles and they look beautiful! What I loved most was how professional everyone was. The crew showed up on time, worked efficiently, and actually cleaned up better than I expected - you’d never know they were even here. They were also super patient with all my questions (and I had a lot!). The quality of their work is top-notch. You can tell they really care about doing things right, not just getting it done quickly. My neighbors have even commented on how great the roof looks. If you’re in the Lake Oswego or Portland area and need roofing work done, I’d definitely recommend giving Elm Construction Services a call. It’s such a relief to find a contractor you can trust who actually delivers on their promises!"

"Went very well and better than I could have hoped for. Very impressed with professionalism and responsiveness. Work was done quickly/efficiently. They cleaned up the worksite several times during the day and left things neat/tidy when they left at the end of the day. I plan to hire them again for some work on my deck. I highly recommend this company. P. Johnson Wilsonville, OR"

FAQs for basement remodeling projects in Welches, OR

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
