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

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.

Five Stars, but a 10/10 for everything. From initial contact meeting with Lucas & Isabel Kelly to get an estimate, through DJ measuring for the door replacement and overseeing the project from start to finish, to Lacey Newton, this company provides excellence in customer service and communication, friendliness, care for customer satisfaction and they are right on top of any requests or issues. They are available, visible, and provide prompt service. And the price is great... I highly recommend this company. The best part of my project, which replaced old siding on one side of my house was Brandon & Curtis. Brandon, the general contractor, did a phenomenal job prepping and putting up the new siding with precision and great attention to detail. Everything was level, matched up, and was installed well above and beyond my expectations. He & Curtis also installed the door and it works like a charm, is hung perfectly, opens and closes very softly with no hiccups. He & Curtis showed great care for my property and cleaned everything well when completed. He and Curtis make a great team and were great to work with throughout the installation. If you want it done right, Brandon's your guy!!! The Painters came in, did an awesome job on the paint, which had to be matched to the rest of the house - good job - and were done quickly, caring for my property and cleaning up well when done. I am planning more work on my home and will have Sister Siding back for the next round when the time comes. My thanks to Brandon, Curtis, DJ, & Lacey especially for running a smooth project that rewarded me with a a beautiful resided home and an awesome new front door. And my special thanks to Brandon - he knows his stuff, is well experienced and takes a great deal of pride in the quality of his work, as well as customer satisfaction.

We needed a siding repair and repainting of our 1950 era home. From the initial estimate to the color consult to the siding repair down to the final coat of paint working with Sister Siding was seamless and easy and came in right on time. And Lacey in the office held our hand all the way. Our little bungalow is the talk of the block! We are so happy with the job and would recommend Sister Siding to anyone who asks. Well done.

Nice people, easy to work with. Finished on time within budget. The entire onboarding process was very streamlined. All of the necessary documentation, including the COI, lead certification, insurance information, and other required forms, was easily accessible online, making it very convenient to review and sign everything. Would hire again.

These guys rock. We needed a couple small sections of LP siding replaced and then the entire house painted. Our house is not at all straightforward: sitting on a hill, it has 3-story faces on the downhill side (a complete nightmare for this kind of work). I had multiple employees from Sister Siding mention that painting was all about "preparation, preparation, and preparation", which is exactly how they operated. They spent multiple days cleaning, caulking, and taping prior to any paint going on the house. Their follow-up afterwards was also amazing, making sure we were happy with the outcome and making final touch-ups a standard part of their process. The result is beautiful. Finally, Lacey and DJ were an absolute pleasure to deal with. They were enthusiastic about our project and very respectful and understanding in all our interactions. A++.

Davis, Lacey and DJ were great to work with and the construction crew did an amazing job with the dry rot repairs. They were very thorough and quoted less than two other contractors I had spoken with, making sure only to fix what was needed. I highly recommend Sisters Siding for any siding repairs!

We had some dry rot issues at our new place. Sister Siding was prompt and professional at getting our needs met, and even better at communicating when additional issues were found beneath the surface. I would recommend giving them a call for your siding needs.
