At Sister Siding, we specialize in repairing and replacing rotted or damaged siding for homes across the Portland Metro Area. Whether you’re dealing with dry rot, water damage, cracked siding panels, or missing boards, our team provides lasting solutions that protect your home and restore its appearance—without pushing you into a full siding replacement if it’s not necessary.

We understand the unique challenges that Pacific Northwest homes face. Rain, moisture, and fluctuating temperatures can quickly take a toll on your home’s exterior. That’s why we offer professional siding rot repair and targeted siding replacement using the highest-quality materials designed to hold up against Portland’s climate.

Common Signs of Siding Rot or Damage

Even minor siding issues can lead to serious problems like mold, structural damage, or pest intrusion if left untreated. Our team can assess the damage and provide targeted repairs that match your existing siding—saving you money and extending the life of your exterior.

  • Soft or spongy areas on siding panels

  • Peeling paint or bubbling caulk

  • Gaps or cracks around windows and doors

  • Warped or bowed siding boards

  • High energy bills or drafts

  • Visible dry rot or discoloration

We Use The Best Siding Materials For The PNW

Our expert team will assist you in reviewing your options, taking into consideration what’s best for your home and your budget.

T1-11

A sturdy plywood siding with a grooved pattern, providing a classic wood-panel look that adds durability and charm to your home’s exterior.

Hardie Plank/Hardie Board

Robust fiber cement siding panels, crafted to mimic the natural look of wood while offering exceptional durability, low maintenance, and resilience against harsh weather conditions.

Stone Veneer

A thin, lightweight alternative to natural stone, more cost-effective, easier to install, and requiring less structural support.

Fiber Cement

A durable and versatile material made from a mix of cement, sand, and cellulose fibers, providing your home with a long-lasting, low-maintenance exterior that can mimic the appearance of wood, stucco, or masonry.

Cedar Shake

A natural and rustic charm to your home’s exterior, crafted from genuine cedar wood shingles for a timeless, textured look that brings warmth and character to your surroundings.

Board & Batten

Wide vertical boards with narrower strips (battens) covering the seams, creating a classic, farmhouse-style look that adds visual interest and a touch of rustic elegance to your home’s exterior.

Dry Rot: What It Is and How It Affects Your Health

Dry rot is a silent destroyer that can eat away at your home’s structure before you even know it’s there. Once it takes hold in moist wood, it spreads fast, weakening beams, warping siding, and putting your home at risk from the inside out. If ignored, dry rot can cause thousands in repairs and even compromise your home’s safety.

In this article, we’ll break down exactly what dry rot is, the hidden ways it starts, and how it can affect not just your home, but your health. You’ll also learn the early warning signs to watch for and why trying to handle it on your own could make things worse. If you think you might have dry rot, you’ll want to read this before the damage gets any worse.

The star I gave reflects the basic work done as in the end, the job was completed but with a lot of work involved to get to the end. Problems with communication from the first rep to the office staff were never resolved. Plus the workers had to return to complete the job after I noticed that the workers had overlooked an area. I'm not happy about working with this group, though I have to say that the final repair and the paint work was satisfactory. It was just too much work to coordinate and make sure things were completed well that turned me off of this group.

We loved working with Sister Siding from start to finish. Lucas showed up and listened to what we wanted but also offered great suggestions. Got a quote quickly. Great communication during the entire process. The team was amazing....They modernized our old 1970's split and we our so happy with it! Their craftsmanship is impressive. I would definitely recommend their services!

From my very first interaction with Lucas, I could tell he was knowledgeable and genuinely wanted to help us make the right decision for our home — not push us into a sale. Throughout the process, Lacey and DJ kept us informed about the timeline and what to expect, and were always quick to respond whenever I had questions. We've owned our 78-year-old house for 13 years and have had many work crews come through. Sister Siding has been one of the most pleasant experiences we've had. I have a keen eye for detail and admittedly high expectations, but every request I made was met with positivity and professionalism. Arseny went above and beyond to make sure I was completely pleased with the final results!

This company is great! DJ called our company needing some plumbing extended as they were replacing the siding for a house in Hillsboro, DJ was great to work with, he treated his crew well and I really appreciate his response times. Super happy and would totally work with them again!

Reedville Youth Baseball is a non profit organization in Hillsboro. I reached out to Sisters Siding about a new roof, new siding and gutters for our snack shack at one of our locations. From the initial meeting with Lucas to give us an amazing quote, to the amazing work done by brothers Josue and Cesar, their father who did an awesome job on an unexpected and much needed concrete repair , the whole process was well explained and the work done was professional and on time. Thank you to DJ and Lacey for sending us an awesome crew to work with.

Great experience! Both the siding crew and the painting crew were very courteous and professional. They kept the work site clean and made sure I was happy with every aspect of their work. The finished product looks great. No short cuts, quality work. We would highly recommend them. Project Managers for every aspect of the job were responsive and communicated throughout the job. One of the best experiences I have had with a contractor.

Sister Siding was easy to work with from start to finish. Lucas showed up on time and was very good getting me the estimate and was flexible to allow for differing options I was interested in. Decided going with Hardie lap siding and a full exterior paint. The crew showed up everyday on time, had good craftsmanship and did good work and kept the worksite clean and organized. After the siding was done, Sister had JK Paint come out and do the full paint job. Again the crew showed up everyday they were scheduled on time and did a great job. Completely happy with the quality of work and the fair price. Definitely recommend.

I was very pleased with the work performed by Sister Siding. Holden kept me informed on the job status. He scheduled the work of Andrey around the schedule of the plumber. Andrey arrived according to the plan, did a quality job, in a timely manner. Andrey gave us options on the trim style and location. There was good coordination from start to finish.

Sister Siding has been incredible from start to finish with our exterior siding project. Project estimator Lucas showed up on time, assessed and measured, and was up front with the likelihood of the project coming in higher than some local contractors. He then sat down, on site immediately, and explained the estimate with us - which came in mid-range for where we’d received estimates for the project from other contractors. He then shared the different options for paint and other upgrades that we had available - in addition, some perks to scheduling siding work over the winter. We were so impressed with the professionalism that we knew we would go with Sister Siding. They worked with us on a date that made sense. Communication and expectations were set clear & the project manager Holden was so easy to talk to, get ahold of, and ask questions to. Dennis and the siding team on site were professional & limited their impact where they could. Additionally - their work directly with JK Paint and seamless process makes it so easy to do a siding/paint project with low stress. Bonus! They have a paint consultant that will come to your home & help you decide on colors with a massive catalog to choose from. Such a useful experience! Overall - LOVED working with a small owner-operator business with no ties to giant contractors in the area. It’s clear this small company cares about your experience as customers & I can’t say more about positive customer service. A few small issues: 1) We had an issue with the window trim, where after the project mostly wrapped the siding team opted to not trim two windows due to an existing vinyl trim. We specifically asked for them to be trimmed aesthetically in the contract. It was just a miscommunication. They came back & redid the work in a professional way & fixed it up immediately! 2) We had to ask them to do a second clean-up due to dust from cutting the Hardie. Also - there was trash left in the driveway after the remaining materials were picked up. 3) At the beginning, communication was a little clunky. We had set a date for project start and the morning of, I hadn’t heard from the project manager about when the team would arrive. I got ahold of him shortly after 9am, after messaging another team member. Their team got sick & he was trying to pull another team but that didn’t end up working. We pushed the start date of the project. After this though, communication with project manager was almost instantaneous & overly helpful. 4) We had an issue with the exterior light that was reinstalled improperly. They did send out an electrician as soon as I could do some troubleshooting with breakers at home. The electrician was done in literal minutes & the light works just fine now. Summary - if there’s an issue, they fix it right away!
