Siding work in Gresham at a glance
Quality Master installs siding across Gresham, OR, on housing that is almost all from one long building boom. The average Gresham-Rockwood home dates to 1978, and homes of that era were frequently clad in T1-11 plywood panel or early hardboard lap, both of which fail predictably at the bottom edge and around penetrations once the coating gives out. Replacement with James Hardie or LP SmartSide is the usual answer. Gresham permits through the City rather than Multnomah County.

Siding in Gresham
Siding Gresham, OR: forty-year-old panel product, failing on schedule.
Gresham's housing is a record of one building boom. The population went from 3,944 in 1960 to 65,235 by 1990, and the average Gresham-Rockwood home dates to 1978. Housing built in that window was very often clad in T1-11 plywood panel or in early hardboard lap siding, and both are now four decades into a service life nobody expected to be this long.
Those materials fail in a specific and recognizable way. Water gets in at the bottom edge where the panel meets the foundation, and around penetrations - hose bibs, dryer vents, light fixtures - where the original caulk gave up twenty years ago. The panel swells, delaminates at the plies, and the damage runs upward from the bottom rather than appearing uniformly. By the time it is visible from the street the sheathing behind the worst sections is usually involved.
The useful thing about a cohort like this is that it is predictable. We know where to look on a Gresham house of this age, and the inspection is quick because the failure pattern is consistent. What varies is how far it has gone, and that determines whether you are looking at panel replacement in the affected elevations or a full re-side.
Replacement is generally James Hardie or LP SmartSide. Hardie holds paint longer and is non-combustible; LP is lighter and faster on the large simple wall planes these houses have, which on a ranch or split-level is most of the elevation. Gresham issues its own permits through the City rather than Multnomah County, which is a distinction worth getting right - and the roof on a house of this age is usually due around the same time, which is covered under Gresham roofing. The gutters come off with the fascia regardless.

Before you hire anyone
What Gresham homeowners ask us before signing.
What happens when you find rot underneath?
We open a section before quoting, not after, so you see what is there. The repair rate goes in the written estimate up front, which turns a bad discovery into a number you already agreed rather than a renegotiation with your house half wrapped.
Will the James Hardie warranty actually hold?
Only if it is installed to Hardie's published blind-nailing, clearance and gap specs, and only by a certified installer. We are certified and we build to those specs. An uncertified crew can leave you with siding that looks right and coverage that was void from day one.
How long is my house going to be open?
We work one elevation at a time and dry it in before moving on, so the house is never open across the board. We give a written day count with the estimate rather than a range, and we schedule around forecasted dry days.

Gresham siding FAQ
Siding contractor Gresham, OR questions, answered.
What is T1-11 and why does it fail?
It is a plywood panel siding product used very widely in 1970s and 80s construction, including across Gresham. It fails because it is plywood: once the coating breaks down, water gets in at the bottom edge and around penetrations, the panel swells and the plies delaminate. Forty years is well past what it was realistically good for.
Where does the damage usually start on a Gresham house?
The bottom edge where the panel meets the foundation, and around penetrations - hose bibs, dryer vents, exterior lights - where the original caulk failed decades ago. The damage works upward from there, so what you can see from the street is generally the late stage rather than the beginning.
Do I need a full re-side or can you replace part of it?
It depends how far it has gone and we will tell you honestly. If the failure is confined to one or two elevations, replacing those is a legitimate and much cheaper answer. Where water has been getting in for years across the house, and particularly where the sheathing behind is involved, a full replacement is the sound recommendation.
Hardie or LP SmartSide for a Gresham ranch?
Both work. Hardie holds paint longer and is non-combustible. LP SmartSide is lighter and installs faster across the large uninterrupted wall planes a ranch or split-level has, which on this housing is most of the elevation. We will quote both if you want to see the difference rather than being steered.
Does Gresham permit through Multnomah County?
No, Gresham issues its own building permits through the City. Portland is in the same county with different rules again, so a Portland answer does not carry over. Siding replacement itself often does not need a permit, but structural repair found underneath can, and we confirm what applies to your address.
Should I do the roof at the same time?
Worth pricing together on housing this age. A 1978 house is on its second or third roof and the siding is original, so the two frequently reach the end of their lives within a few years of each other. Doing them on one mobilization costs less than two separate projects.
