Sandi and Roger met with us in 2014 to re-build their deck and plan ahead to install a covered porch. After listening to their ideas, we created some drawings in Google Sketchup of what the covered porch might look like. They asked us to build around their lilac bushes, so we designed a covered porch with “clipped corners.”

This created a challenge because it is nearly impossible to frame an exposed beam, vaulted ceiling with clipped corners with wood rafters. We brought in our structural engineer and worked with him to engineer a “flitch” beam, which consists of a 3/16” steel plate sandwiched between 2×8 roughsawn rafters.


After two weeks of framing, the rafters were done and the Tongue and Groove ceiling boards were sealed and installed. Our next step was to re-roof the back portion of their home, then paint, install screens and the skylights.


Sandi and Roger are thrilled with the finished porch and workmanship. Please give us a call if you would like to create a spectacular outdoor living space 541-754-6326.

Our client met with us this spring with the concept of opening up her dated 1950’s bathroom, getting rid of the pink tub and pink sink and making an “Artic” oasis. She wanted to maintain a white with “Artic” green/blue theme. We created some design options using 3D software and presented the options to our client. After some simple revisions to the design and products were chosen within her budget to match her goals we started the remodel.Our exceptionally detailed contract allowed her to understand the scope of the project and be sure that we had covered everything. We also offered electrical safety and insulation improvements. Construction began in June 2015 and was completed in early August (we had some delays with the imported tile).

One of the features of this bathroom is the floating vanity and floating LED backlit mirror. The mirror has color changing LED lights. You can use a small remote control to change the color and brightness to match your mood. This lighting really draws your eye towards the glass tile and provides subtle ambient lighting for nighttime.

She is thrilled with our work and her friends are too. Please give us a call if you’d like to build an spa-like oasis in your home.

Some of the details:

  • Cabinets: Floating “European” frameless with conversion varnish over white paint on maple plywood
  • Countertop and Sinks: Corian Cameo White with a thickened front edge
  • Shower tile: AKDO Thassos Honed Marble 3×6
  • Glass tile accents: AKDO Stagger Fusion Mosaic (Icelandic Blue, Thassos P, Seashell)
  • Tile floor and Base: Emser Pietre del Nord “Vermont” matt 12×24
  • Paint color: Sherwin Williams’ Glimmer – SW 6476
  • Exhaust fan: Broan QTXE110S
  • Lights: Custom design by Radiance by Design, Corvallis
  • Shower Glass: 3/8” tempered heavy glass shower enclosure
  • Tub: Kohler Bellweather cast iron
  • Shower and Faucet: Grohe Concetto
  • Toilet: Toto Aquia

Mike & Tricia asked us to build them a different kind of deck in their back yard. When they came to us, they had already hired Bruce Olsen, a local architect to design their deck. Bruce’s beautiful, hand drawn deck plans featured Asian influences including a copper covered lantern. We provided a contract to build the deck using Trex Earthwood Evolutions composite decking. The handrail, trellis and detailing is cedar.


All of the framework of the deck is pressure treated lumber. As pressure treated lumber is not immune to water damage, we take extra precautions above and beyond standard building techniques. We spray cut ends of lumber with additional rot preservative. We also form concrete around buried posts to cause water to flow away from the posts.

The decking is attached with Tiger Claw hidden fasteners. The cedar is attached with Fastenmaster Split Resistant screws. We take extra care when installing our handrail posts to be absolutely certain they will remain rock steady for the life of the deck. We use galvanized through bolts and Simpson DTT2Z hardware to ensure that you won’t have that “wobbly” feeling in our posts five years after we leave.


We noticed during construction that some details of the deck design might not work for our customers. The bench was designed to be very low, common in an Eastern deck, but not very popular in the West. We also felt that some sections of the handrail could be changed to better suit the landscaping in the back yard. We generated three dimensional drawings of some sections of the deck and talked with Mike and Tricia about our concerns. Working with Bruce and the owners, we came to a solution that worked for everyone involved.


We built the framework for the copper lantern and took it off site to a fabricator who installed standing seam copper. The lantern has frosted glass walls with clips to allow easy removal for cleaning. Inside is a simple LED bulb. We were able to build it so the wire is completely hidden from view and goes to a switch just inside the back door. The lantern looks lovely at night. We also custom built housings for two mail-order planters Mike and Tricia picked out.


A lot of elements came together to make this deck. Bruce’s vision is extraordinary. G. Christianson Construction’s building know-how, and foresight caught many potential issues before they became problems. Our lead carpenter and our office staff came up with many innovative solutions to the special set of challenges in building this one of a kind deck. Call us today to make your dream a reality!

Gerry and Carroll invited us to their home in July 2014 to look at replacing their dated tile countertops and updating their backsplash. While updating their countertops, they chose to upgrade their sink to a Blanco Diamond 1 ¾ Metallic undermount sink and we re-installed their existing faucet. They picked out Coastal Green granite and we repainted the kitchen walls to match.



For the backsplash, the owners chose glass tile. Glazzio Glacier 4×12 glass GL88 glass tile and Crystile 4×12 glass tiles provide depth and interest to the backsplash. The pops of color in the backsplash incorporate beautifully with the colors of the cabinets, counter tops, appliances, and paint. To further highlight the gorgeous backsplash and to provide additional task lighting, we installed new LED strip lights throughout the kitchen.


In the design phase, we located the original cabinet makers and arranged for them to come in and touch-up the cabinets. Now the cabinets look as good as the day they were originally installed. We installed new window sills and trim and re-lacquered them to match the existing woodwork. We replaced the dated appliances once we finished installing the new countertops.

Carroll and Gerry are very happy with their updated kitchen. They were grateful to our crew especially during tile countertop demolition for their care and attention in not damaging the existing cabinets. They were also very impressed that we were able to get the demolition, countertops, plumbing, appliances and backsplashes completed in one week so they could start cooking again.

Main dining room.

In late August, the Old Spaghetti Factory called us to find out if we could help them remodel the historic rail depot that once held Michael’s Landing and Terminus restaurants. They had an aggressive schedule to open by mid-November and didn’t know any local craftsmen. We offered to help and Old Spaghetti Factory hired us to provide the framing and structural repairs required to reinforce the historic building and bring back its splendor. Cascade Design provided structural engineering and gave direction for replacing a few posts, reinforcing an old timber beam and reinforcing a steel beam.


Upper dining room.

G. Christianson Construction has had our crew of three trim carpenters working at Old Spaghetti Factory for three weeks and expect to finish on schedule. The crew salvaged the old interior trim and re-milled the old vertical grain Douglas fir for reuse.  We are installing new Poplar post wraps, corbels and trim. On the main level we pulled the historic windows, refinished and re-installed them. Next we installed Lauan wainscot paneling, battens, top rail and trim.  After that, we installed built-up trim around the existing windows to mimic the historic trim. We are very excited to help restore an exceptional piece of Corvallis’ history.

Here are links to articles about this project in the Corvallis Gazette Times:

Here are some helpful tips of things to consider and areas to look at to keep your deck in great shape and to spot when you need to repair your deck.

Split or decaying wood: Check several different areas of the deck to be sure the wood is still sound. This includes the ledgers board (where the deck attaches to the house and a common source of deck failure), support posts and joists under the deck (if you can reach them), deck boards, railings and stairs.

Pay special attention to any areas that tend to remain damp, are regularly exposed to water, or are in contact with fasteners. Use a tool like an ice pick or screwdriver to penetrate the wood surface. If you can easily penetrate ¼ – ½ inch, break off a sliver of wood without splinters, or the wood is soft and spongy, decay may be present.

This is also a good time to look for small insect holes in the wood, which may indicate insects.

Flashing: Flashing is a metal or plastic guard that directs water out and away from sensitive areas. It’s often installed where the deck and house come together, keeping moisture and debris from collecting between the house and the deck’s ledger board. Be certain the flashing is sound and firmly in place. Consider adding or replacing flashing if you notice areas that are obviously allowing water to collect.

Loose or corroded fasteners: Fasteners include nails, screws or anchors in the ledger board. Tighten any loose fasteners, and pound in any nails that have popped up. (Note: the ledger board should not be fastened with only nails.)

If a fastener appears rusted or corroded, consider replacing it. A corroded fastener can cause deterioration in surrounding wood.

The deck or stairs should appear even without sagging and should not sway or move when tested.

Railing and banisters: These should be secure. Push on them to be sure there is no give.

Also, check to be sure they are high enough (most code require a 36” high railing and usually encourage 42” high railings) with rails no more than 4” apart (measured from the inside of the rails) to keep small children and pets from squeezing through. This is especially important the higher your deck is off the ground.

Stairs: Check any railings or handrails to be sure they are firmly held in place; check also the risers and stringers to be certain they are securely attached and not decayed.

If the area behind the stairs treads is open, this opening should be no more than 4” high.

Also, always keep stair pathways clear of planters, décor, toys and other items that can present a tripping hazard.

Cleaning and maintenance: Clean away any leaves and debris, since these can be slippery and promote mildew.

If mildew is present or the deck coating has worn away, make time to clean and apply a new waterproofing coating. It can help prevent the split, decayed wood and loosened fasteners mentioned earlier.

Grills, fire pits, chimneys, heaters and candles: These features can create a warm and cozy deck atmosphere, but make sure any source of fire or heat is safely placed away from the flammable surfaces or that the deck surface is protected by a non-flammable pad.

Always use caution and follow manufacturers’ directions.

Lighting and electrical: Be sure all lighting is working; clean any light covers to allow maximum light to shine through, and trim any plants or tree limbs that may be blocking light.

If you don’t have adequate lighting, there are a lot of great new deck lighting products you could consider to illuminate your steps and pathways.

Be sure all electrical outlets, appliances and features are up to code, in good condition, and childproof if children are present.

Watch that any electrical cords do not present a tripping hazard.

Outdoor furniture and storage: Test all outdoor furniture to be sure it is sturdy. Avoid placing seating right at the edge of the deck. If you have a swing or hammock installed, test the chains and ropes to be sure they are secure. Consider installing childproof latches on any storage boxes and benches.

Be sure to keep all deck related chemical products stored safely away from children, including BBQ lighter fluids, matches, cleaners, etc.

Surrounding trees: If you have trees overhanging your deck, make certain there is no danger of decaying limbs breaking free and falling from trees surrounding the deck.

Nik and Angie wanted to do some major remodeling to their home that was built in 2002. The major additions were a new master suite and bath, additional garage bay, and a new craft and bonus room. They also wanted to update all of the bathrooms in the home, replace the existing heating/cooling systems, replace carpeting in five areas including the new craft and bonus room, install new organizing rods and drawers in the master closet, add a special coating to the floor of the garage, expand the driveway, add a gas line to the patio for the grilling, replace all of the windows in the home, and add eight skylights.


The new Master Retreat and closet have Oak hardwood flooring throughout. New Milgard Montecito windows let a lovely amount of light in, complimented by three Velux skylights. In the Master Retreat bathroom, Wichita art glass has been added to the picture window to add some unique detailing. The Master Retreat bathroom has heated Travertine tile floors. The cabinets are Huntwood Rustic Alder cabinets in an Arroyo style with under-mounted Kohler sinks and Marble countertops. The countertops and flooring are complimented by Mosaic Cabernet glass accent tiles. The flooring in the shower is a sliced olive stone.

In the other bathrooms, the same marble, cabinets and flooring were installed. Toto ADA toilets were added to all the bathrooms and all doorways were widened to make the home adaptable if the homeowners wish to Age-In-Place. A curbless shower was installed in the Master Retreat bathroom to reduce the tripping hazard. A vanity area was created for Angela so she can sit and relax in her Master Retreat and to have an area with special task lighting.

Multiple niches were created in all of the showers to add needed shelving storage in the showers. Seats were added to the Master Retreat shower and the Hall bathroom. A Velux skylight was installed into the Hall bathroom to provide extra lighting as there are no windows in this bathroom. A Symphony Aquatic Air tub was installed into the Master Retreat bathroom and a Fiber Fab soaking tub was installed into the Guest bathroom. All hardware is Oil Rubbed Bronze by Moen and Delta.


In the craft and bonus room, guest room, stairs, den, and office we installed Tuftex Venecia Fantasia 527 carpet. Velux skylights were installed into the bonus room and into the craft area with remote controlled electric blackout blinds. New Milgard Montecito windows let a nice amount of light in, complimented by four clerestory windows. All paint is Sherwin-Williams’ Duration Home for all walls and ceilings.


The entire remodeling project took 10 months to complete and included nine additional jobs requested during the remodel. Nik and Angie are thrilled with the completed project and look forward to living in the home for many years to come!
