"Was told that we where gonna get taken care of and they would make it nice for us but then we where treated like bottom of the barrel crap because they gave us a good deal. Only had one guy most of the time and he came and went as he pleased then I did the demo and then was treated like I was supposed to help more then when 1 other guy showed up once they worked for 4 hours got the frame of the deck up and a few deck boards on but they didnt level the ground or the deak didnt clear any of the crap plants etc underneath the deck then didnt support the middle of a 10ft deck it was just bs a pretty horrible experience all together "

"We have been wanting to convert our tub to a walk in shower for years. We are grateful that we found Fusion builders. Daniel the project manager and his team made such a masterpiece. All the details and our request are perfectly done. We requested for shower nische, floating vanity & mirror with lights, high tech toilet with heated seat, bidet and more. Working with them is smooth. Great craftsmanship, professionalism and communication. We will hire them again for our future home updates. Highly recommended! "

"Jordan worked on our home and he did an impeccable job. He always kept us informed of what the next step would be and treated us with great respect. He was here rain or shine and always put in a full hard day's work. He always cleaned up at the end of the day. I highly recommend Jordan for your job. If I ever need work done again, I will certainly hire Jordan."

"I hired ELC construction for my tenant improvements work. They have all the paperwork needed to meet landlord’s and city’s requirements. The main owner of this business is Hector and he is very professional and very committed to the work. Man of his words and is very transparent on his words and communication. Honest contractor and is very hard to find one these days. I can’t thank him enough for the work he did in our space and I’ll be hiring him for my residential project as well. His pricing is reasonable and I’m a very happy customer. For all construction needs and electrical plumbing needs they are the pros. He is bit slow on the documentation side. if your project needs documentation, be patient, he has all documentation. But he has definitely improved on that since I hired him few days ago. Apart from that a solid five stars for him and I wish he gets many projects. "

FAQs for basement remodeling projects in Vashon, WA

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.
