Attachment 2 - Letter From Mark Hulbert, dated February 3, 20251315 Walnut St., Berkeley, CA 94709 510 418 0285 mhulbert@earthlink.net February 3, 2025 17121 Wild Way, Los Gatos Historic Window and Door Recommendations The following report summarizes historic architectural considerations and recommendations for the extant windows and doors of the subject residence. Existing windows are traditional industrial steel units, mostly operating casements, several fixed, all with true-divided lites, of which there are some 40 units. There are also 2 pairs of steel doors. Other doors are hardwood plank at front, or painted wood with divided lites at side and rear. In sum, multi-lite steel units, while traditional, are an unfortunate choice for residential construction, as older single-glazed steel units are ultra-lean and lightweight, leak moisture and air excessively so, at this approximately 100-year juncture, have minimal thermal effectiveness and challengingly high maintenance requirements. At Wild Way, this reality is in clear evidence as even interior faces of steel sashes have rusted. As these steel doors and windows are challenging both in terms of the lack of thermal and waterproofing qualities and resulting maintenance requirements, and as insulated windows and doors are recommended for fire prevention, I firmly concur that replacement is needed. Towards which, the following considerations and recommendations are intended to satisfy architectural and historic architectural requirements: 1. As the existing units are metal, replacement exterior material should be similar so that the exterior appearance is similar. 2. While new high quality thermally rated steel windows are available, they are by far the highest cost option. While fiberglas replacement windows are also an option, the exterior material and profiles would not match the existing historic. 3. Aluminum doors and windows are an alternative, whether full aluminum or aluminum exterior clad, the latter the more residential and more available option. 4.Replace the existing windows (figs.4-5) with exterior aluminum clad units with exterior design and details similar to the existing originals. Multiple manufacturers produce standard windows. Yet, based on recent experience, only several provide custom details to effectively replicate historic windows and doors – in particular exterior casings and muntins molded to replicate historic profiles (figs.6-7). Such window and door manufacturers include Marvin (Ultimate series) and Andersen (E-series), which are the recommended and equivalent replacement options (see product literature https://www.dropbox.com/scl/fo/r00ni0he48lhhp2ss2v03/AB7UgDesWLIui_- HCZEVfh0?rlkey=u94jll0xr7aqobb9si82q3u8p&dl=0). 5. The ornamental hardwood front door (fig.8) should be retained, repaired and refinished. Other exterior doors (fig.9) should be replaced with aluminum clad units. 6. Replacement doors and windows to be thermally glazed with “simulated” divided lites and with slender exterior grids (i.e., “muntins”) to match the existing. 7. Entire window and door assemblies require replacement, so complete existing assemblies, including frames, require removal and replacement with thermal- and water-proofed assemblies. 8. Per attached photos (figs.10-12), a range of unique windows should be replicated to be similar to the existing originals include: •The living room bay window does not have molded casings but has flat casings, which exterior appearance the replacement assembly should replicate.
